  原标题:贸易战正酣,中国大使正告美国:没有人能阻止中国统一,咱拭目以待!


  [环球网综合报道 记者 朱梦颖]“我们拭目以待,看看会发生什么!”

  中国驻美大使崔天凯3日接受中国国际电视台(CGTN)英文频道《对话》(Dialogue with Yang Rui)专访,并就美国总统特朗普近日所签署的“台湾旅行法”及台湾统一等问题发表看法。

  在接受CGTN专访时,中国驻美大使崔天凯明确表示了对1979年通过的“与台湾关系法”及特朗普签署的“台湾旅行法”的反对,重申“一个中国”原则。崔天凯还表示,可以肯定的是,“没有人能阻止中国统一。我们寻求和平统一,如果这种方式不行,我们就用别的方式”。

  在谈到破坏“一中”原则是否会引爆战争时,崔天凯回应称,“我们拭目以待,看看会发生什么”。

  以下为访谈实录:

  主持人:就在不久之前,“台湾旅行法”几乎全票在美国通过,这个法案对于台湾来说是一个危险的信号,美国正准备历史性地和台湾实现高级官员互访。这个法案加上1979年通过的“与台湾关系法”,这两个都是美国通过的法案。你怎么看未来大陆和台湾开展对话的可能性?美国是否是中国统一最大的一个障碍?

  崔天凯:我们一开始就反对这个所谓的“与台湾关系法”,现在我们的立场也没有改变。台湾对于中国意味着领土完整、国家主权和统一。这个是核心利益,没有妥协余地。我们也希望美国能够遵守之前的承诺,履行三个联合公报的内容。

  主持人:你怎么看“台湾旅行法”带来的后续影响?这种军事人员互访的可能性激发了大陆统一的决心。如果真的军舰真的停靠到高雄,这意味着什么?

  崔天凯:我们反对美台之间任何形式的军事合作,包括美国对台军售。我们紧密注视这些情况,我们也会根据美国的行动而采取相应行动。

  主持人:你是否认为“一个中国”原则仍是中美关系的基石?也是未来任何对话的基础?

  崔天凯:我认为这是中美关系的政治基础。如果有任何人试图破坏这个原则,后果将会很严重。

  主持人:你的意思是,根据《反国家分裂法》,如果有人破坏这一原则,战争将会爆发吗?

  崔天凯:我们拭目以待,到时候就知道了。

  主持人:足矣。

  崔天凯:至少一件事是确定的,没有人能阻止中国的统一。

  主持人:没有人能阻止中国的统一。那最后是武统还是和平统一,能给美国人一个负责任的答复吗?

  崔天凯:我们寻求和平统一,但如果这种方式不行,我们就用别的方式统一。

經濟學人:台灣再成中美關係衝突熱點

2018年4月6日 下午2:50
(中央社倫敦5日綜合外電報導)美國與中國貿易戰升溫之際,英國「經濟學人」最新撰文指出,台灣在安全議題上的重要性再度急遽升高,台灣即使不願成為中美衝突熱點,也無法避免。

最新一期英國「經濟學人」(Economist)以「台灣再度成為中美之間的衝突熱點」(Taiwan is again becoming a flashpoint between China and America)為題撰文表示,美國總統川普先是在就職前和蔡英文總統通電話,並在上個月簽署「台灣旅行法」鼓勵美台高層官員互訪,觸怒北京當局。

經濟學人提到,美國友台官員陸續上任,前國務院亞太副助卿薛瑞福(Randall Schriver)出任國防部亞太助理部長,而主張打「台灣牌」反制中國、對台灣恢復外交關係的前美國駐聯合國大使波頓(John Bolton)也出任國家安全顧問。

此外,國務院負責印太策略的東亞暨太平洋事務局副助卿黃之瀚(Alex Wong)上月訪台,他在發表演說時表示,不能再讓台灣不公平地被排除在國際社會之外。黃之瀚還向蔡英文總統保證,美國對台承諾不會改變。

文章指出,訪問北京的美方要員被告知,台灣旅行法鼓勵的台美交流可能踰越中國的紅線。因此,這個問題比習近平面對的其他兩個重大挑戰更形危險。第一個是關於北韓非核化方面的微妙峰會;第二個是美國對中國出口產品和中國優先的產業政策採取攻擊行動。川普政府3日宣布對中國銷往美國價值500億美元貨品課徵25%關稅。

中國駐美公使李克新去年警告川普不要簽署台灣旅行法,他曾對美國國會議員表示,美國軍艦抵達高雄港之日,就是武力解放台灣之時。中國國家主席習近平上月親自警告,任何「分裂中國」的行動將面臨「歷史的懲罰」。這類警告對台灣造成若干影響。

即使民進黨內對於應該支持台灣旅行法到何種程度,也有不同看法。蔡英文總統本人也出於本能地保持謹慎以避免觸怒中國。沒有台灣人希望淪為大國博弈下的棋子。

文章也指出,美國在台協會(AIT)台北辦事處新址將於6月舉行落成典禮,外傳可能會有一位內閣官員參加。波頓的出席可能真的會讓中國心生警戒,也可能被解讀為川普在貿易議題上利用台灣向中國施壓。習近平首席經濟顧問劉鶴已就縮小對美國鉅額貿易順差和美方密集協商,外界臆測劉鶴可能獲習近平授權,提議削減數百億美元貿易順差,以避免中美之間爆發全面貿易戰。

但倘若中國認為美國在貿易議題後,仍持續要改變台灣現狀,情況又會如何?習近平曾表示,台灣「問題」不能留給後代處理。如今他大權在握,若不動用權力阻止台灣脫離,恐遭國內民族主義者嚴厲論斷。台灣在安全議題上的重要性再次急遽升高,提醒台灣即使不願成為衝突熱點,也無法避免。(譯者:劉淑琴/核稿:林憬屏)1070406

Chinese ambassador is reporting to the United States: Nobody can stop China from unifying

Original title: The trade war is raging, and the Chinese ambassador is telling the United States: No one can stop China's unification, so wait and see!


[Global Network Reporter Zhu Mengying] “We will wait and see what happens!”

Chinese Ambassador to the United States Cui Tiankai accepted an exclusive interview with Dialogue with Yang Rui, the CGTN English Channel, on the 3rd and expressed his views on issues such as the “Taiwan Travel Law” signed by US President Trump and the unification of Taiwan. .

In an exclusive interview with CGTN, Cui Tiankai, China’s ambassador to the United States, made clear his opposition to the “Taiwan Relations Act” passed in 1979 and the “Taiwan Travel Law” signed by Trump, reiterating the “One China” principle. Cui Tiankai also said that what is certain is that “no one can stop China’s reunification. We seek peaceful reunification. If this is not the case, we will use other methods”.

When talking about undermining whether the "one China" principle will trigger the war, Cui Tiankai responded by saying, "We will wait and see what will happen."

The following is an interview record:

Moderator: Just a short time ago, the "Taiwan Travel Law" was almost passed by the United States. This bill is a dangerous signal for Taiwan. The United States is preparing to exchange visits with senior officials in a historical manner. This bill is accompanied by the "Taiwan Relations Act" passed in 1979, both of which are bills passed by the United States. How do you see the possibility of dialogue between the mainland and Taiwan in the future? Is the United States the biggest obstacle to the unification of China?

Cui Tiankai: We opposed this so-called "Taiwan Relations Act" from the beginning, and our position has not changed. For China, Taiwan means territorial integrity, national sovereignty and unity. This is a core interest and there is no room for compromise. We also hope that the United States will abide by its previous commitments and fulfill the content of the three joint communiqués.

Moderator: How do you see the subsequent impact of the "Taiwan Travel Act?" This possibility of mutual visits by military personnel has inspired the determination of the mainland’s reunification. If real warships really stop at Kaohsiung, what does this mean?

Cui Tiankai: We oppose any form of military cooperation between the United States and Taiwan, including US arms sales to Taiwan. We are closely watching these situations and we will take corresponding actions based on the actions of the United States.

Moderator: Do you think the "One China" principle is still the cornerstone of Sino-U.S. relations? Is also the basis for any future dialogue?

Cui Tiankai: I think this is the political basis of Sino-U.S. relations. If anyone tries to break this principle, the consequences will be serious.

Moderator: Do you mean that according to the "Anti-Secession Law," if someone undermines this principle, will war break out?

Cui Tiankai: We will wait and see. We will know it by then.

Moderator: enough.

Cui Tiankai: At least one thing is certain. No one can stop China's reunification.

Moderator: No one can stop China's reunification. Was it ultimately Wutong or peaceful reunification that could give the Americans a responsible reply?

Cui Tiankai: We seek for peaceful reunification, but if this is not the case, we will unify in other ways.

Economist: Taiwan Reached Hot Spots in Sino-U.S. Relations

(Central News Agency, London, 5th, 2008) As the trade war between the United States and China heats up, the latest article from the British “Economist” pointed out that Taiwan’s importance on security issues has risen again and again, even if Taiwan does not want to become a hot spot in Sino-US conflicts. It cannot be avoided either.

The latest issue of the British "Economist" wrote an article titled "Taiwan is again becoming a flashpoint between China and America" and stated that President Trump of the United States first came before his inauguration. He telephoned President Tsai Ing-wen and signed the "Taiwan Travel Act" last month to encourage top U.S. officials to exchange visits and angered the Beijing authorities.

The Economist mentioned that U.S. friendly Taiwan officials have taken office one after another. Randall Schriver, the former Deputy Assistant Secretary of the State Council’s Asia Pacific Region, served as the Asia Pacific Assistant Minister of the Department of Defense, and the former U.S. advocated the “Taiwanese card” to counter China and restore Taiwan’s diplomatic relations. Ambassador to the United Nations John Bolton has also served as a national security adviser.

In addition, Alex Wong, deputy assistant secretary of the East Asia-Pacific Affairs Bureau of the State Council responsible for the India-Pacific Strategy, visited Taiwan last month and said in his speech that he could no longer let Taiwan be unfairly excluded from the international community. Huang Zhixuan also assured President Tsai Ing-wen that the United States’ commitment to Taiwan will not change.

The article pointed out that the American officials who visited Beijing were told that Taiwan-US exchanges encouraged by the Taiwan Travel Act may exceed China’s red line. Therefore, this issue is more dangerous than the other two major challenges that Xi Jinping faced. The first is about the delicate summit of North Korea’s denuclearization; the second is the US’s attack on China’s export products and China’s priority industrial policy. The Trump administration announced on the 3rd that it will impose a 25% tariff on China’s $50 billion worth of goods for sale to the United States.

Li Kexin, the Chinese ambassador to the United States, warned Trump last year not to sign the Taiwan Travel Act. He once told members of the US Congress that the day the US warships arrived at Kaohsiung Harbor was the time when the armed forces liberated Taiwan. Chinese President Xi Jinping personally warned last month that any action to "splinter China" will face "historical punishment." Such warnings have had some impact on Taiwan.

Even the DPP has different views on the degree to which it should support Taiwan’s travel law. President Tsai Ing-wen has also been instinctively cautious to avoid angering China. No Taiwanese want to become a pawn under the game of a big country.

The article also pointed out that the new site of the Taipei Office of the American Institute for Taiwanese Affairs (AIT) will be inaugurated in June. There may be a cabinet official in the outside. Bolton's attendance may really make China vigilant, and may also be interpreted as Trump's use of Taiwan to exert pressure on China on trade issues. Xi Jinping, chief economic advisor to the United States, has narrowed his huge trade surplus with the United States and intensive US negotiations. The outside world speculates that Liu He may be authorized by Xi Jinping and proposes to cut tens of billions of U.S. dollars in trade surpluses to avoid a full-scale trade war between China and the United States.

However, if China believes that the United States continues to change the status quo in Taiwan after the issue of trade, what will happen? Xi Jinping once said that Taiwan’s “problems” cannot be left to future generations. Now that he is in power, if he does not use power to prevent Taiwan from escaping, he will be severely criticized by domestic nationalists. Taiwan’s importance on the issue of security has once again increased rapidly, reminding Taiwan that even if it does not want to be a hot spot for conflict, it cannot avoid it.

换推力矢量后歼20战翻F22不是梦 眼镜蛇机动只是小菜
换推力矢量后歼20战翻F22不是梦 眼镜蛇机动只是小菜

0
  最近网络上出现了不少歼10战斗机的推力矢量高清大图,这会给歼10战斗机提升多大能力?而推力矢量是提高机动性最佳黑科技,没有之一,我们不禁要问,假如歼20也换装推力矢量技术的话,飞机能有多少翻天覆地的变化?能不能一手搞定F22,F35战斗机?

wut3-fysuuyc0825836.jpg
歼10B战斗机终于装上了全向推力矢量发动机
V11_-fytnfyn9392008.jpg
注意尾喷管分裂比较大,而且减速伞舱开了个缺口躲避发动机喷管
  当然,要搞清楚这个问题,先看看美国俄罗斯推力矢量技术,究竟有多牛。

  简单一点,从中国人民的老朋友苏27战斗机说起,眼镜蛇机动就是苏27的招牌动作,群众津津乐道,其实这个东西华而不实,就是一个不受控的上仰自然恢复过程,飞行员在时速400公里到过500之间平飞,飞机不带坡度和侧滑,呼啦一下将操纵杆拉到底,眼镜蛇就起来了,起来以后飞机姿态会慢慢的自动恢复成平飞模式,不过整个过程中,飞行员必须断开迎角限制器,否则飞机起不来。

HgFT-fysuuyc0825890.gif
眼镜蛇机动的典型示范
  正因为苏27做眼镜蛇机动的时候,限制很多,而且机头拉起来之后,飞行员不能随意做动作,必须等飞机自己恢复之后才能接手操纵,假如飞行员急躁了点,没等飞机恢复就开始动作,这很可能带来失控坠毁的悲惨结果,所以俄罗斯的眼镜蛇操作要求很严格,不是一个可以正常使用的动作,做表演很赏心悦目。

  在欧美一片质疑声中,俄罗斯人并没有停下脚步,而是跟随美国F15和F22的步伐,给苏27装上了推力矢量喷管,终于让苏27家族飘了起来,不仅眼镜蛇机动性,黄鼠狼机动都随便做。

otxR-fysuuyc0825921.gif

  这就是眼镜蛇机动的增强版-黄鼠狼机动性,不过速度限制还是类似的,毕竟酥27骨架脆嘛

  歼20战斗机设计,采用了升力体鸭式布局设计,飞机具备高机动和隐身性能,核心要求超音速阶段,超音速巡航击毙敌人是非常爽的事情,亚音速不作为核心要求,虽然如此,现阶段歼20战斗机在不采用推力矢量技术的情况下,照样做到了60度迎角可控,这个指标赶上了美国F22。

  难道歼20换了推力矢量技术之后,只能做这种眼花缭乱的黄鼠狼机动了吗?黑科技仅仅用来作秀?

  当然不是,推力矢量有巨大的收益,尤其对于空中优势战斗机,这个不是单纯的作秀。

  采用推力矢量喷管改变喷气流的推力方向为操纵飞机直接提供附加的力和力矩; 二是根据飞行的需要 将推力矢量控制与飞机气动舵面控制相互协调匹配起来进行综合控制从而满足飞机对提高机动性能的进一步要求,这就是俗称的飞行控制系统,火力控制系统,发动机控制系统三合一。

  推力矢量,分成二元和三元,最早使用的就是F22战斗机,这是一种二元喷管,外表长方形, 其主要指标是 推力矢量角为正负20 度,角速度为 45 度/秒,后部外廓尺寸扁平,大大降低了尾阻和后机身阻力,使得F22不仅机动性能优良, 而且对红外隐身有很大好处,而且利于超音速巡航,这种喷管的缺点是结构比较笨重,一个发动机增重将近200公斤,内流特性较差,高温气流从圆形的燃烧室转到方形喷口,会损失3-5%的推力,外加F22的大S进气道,相比苏57的直通进气道压力恢复系数也有3%以上的损失,从结果来看,F119发动机的二元推力矢量设计,让F22达到了无与伦比的隐身和超音速巡航,物有所值。

8OFu-fysuuyc0825970.jpg
F22的扁平推力矢量,雷达隐身好,红外隐身牛,就是太重,太吃推力
  二元推力矢量最早批量应用,但是在流动损失和增重上,让人完全吃不消,所以科学家又展开了更轻更好的推力矢量研究,这就是三元推力矢量,就是圆形的可动屁股,学名轴对称矢量喷管。

  轴对称矢量喷管 有两种方案: 第一种是俄罗斯的笨重方案,圆柱段轴线偏转矢量喷管 其主要特点是把喷管的圆柱段分为前后两截 在搭接处的左右两侧设置了两个侧向销轴 这样后段的排气喷管(即轴对称喷管的收敛扩散段)就可做俯仰平面内的上下摆动 从而获得附加的操纵飞机的力矩,该装置的优点是运动原理非常简单, 原轴对称收敛扩散喷管可以不做任何改动,其缺点是转动段长度达1.3-1.7米,而且转动部件靠前,不仅外阻很大,而且结构上受到的附加载荷很大 另外圆柱段转动带来密封问题,这些都使之结构较复杂,重量增大太多,除了战斗民族,全世界都不敢玩。

uHj2-fysuuyc0826008.jpg
苏35的推力矢量喷管,太长太重,吓死人
  第二种就是扩散段气流偏转的轴对称矢量喷管,该方案完全保留了轴对称收敛扩散喷管的良好气动性能 只是在结构上扩大了扩散段的功能 使之既产生超音速气流 ,又能按飞行需要偏转气流方向,由于气流偏转是在扩散段内实现的 所以它的气动载荷要小得多,它的操纵动作系统可以做得比较轻巧,另外它是在出口截面上实现喷气流偏转的,所以新增力矩也最大作用效果最佳,该方案得到了飞机设计师和发动机设计师一致赞扬,其突出优点是飞机不需要作较大的改装即可实施, 新旧飞机都可安装 很容易在现役飞机上作此项技术的试验验证,这就是歼10B战斗机现在的推力矢量技术。

  GE的轴对称矢量喷管(AVEN),可任意方向偏转17度,尾喷管偏流片成环形排列成一圈,通过以 120 度间隔布置的 3 个液压动作器控制偏转,动作器拥有独立的动力单元。另外AVEN技术可用于任何一架F-16上。

  我国太行发动机也有类似的改型,预计相同的技术也将应用在歼20战斗机上。

中国太行推力矢量控制装置,3个活塞杆推动
  推力矢量的好处在哪里?

  格斗无敌:

  推力矢量可以几乎无限制增加飞机的可用迎角,三代机的迎角范围大部分都是24-26度,多了就要失控,在空战中要获胜,就必须提高飞机的敏捷性 为飞行员快速调转机头,扩大使用迎角(F-l6 的使用迎角限制在 25 度 而 F-22 的则已扩大到 60 度) 则一定要采用推力矢量技术。

  隐身更牛:

  采用推力矢量喷管进行飞机后体与排气系统一体化设计,可使飞机尾翼面积减小,其雷达反射截面也会相应减小,从而提高飞机的隐身性能,F-22 战斗机采用的二元矢量喷管与后机体进行一体化设计,其大宽高比二元喷管9可大幅度降低喷管射流的红外辐射强度明显地改善隐身性。

T56A-fysuuyc0826059.jpg
这就是美国发动机推力矢量最佳方案之一,我国太行发动机设计也类似
  超音速巡航更牛:

  超音速巡航,要求发动机不开加力就使得飞机具有超音速巡航能力,一方面是提高飞机的不加力推力; 二是减小超音速飞行时的阻力,提高飞机的升阻比, 采用推力矢量技术, 并与飞机进行一体化设计,可使飞机的阻力减小,重量减轻对超音速巡航有利。

  推力矢量化不仅因喷流升力而提供直接升力增量,还因喷管靠近机翼后缘,喷流对机翼形成超环量而提供部分间接升力增量,飞机阻力减小,阻力减小了航程当然增大,飞机重量也可以减轻,可使有效载荷增大,美国对于采用二元推力矢量的研究,航程提高程度从2%-21%不等,假如参数选择合理的话,收益还是很可观的。

  下面让我们看看推力矢量的真实威力:

itQI-fysuuyc0826087.jpg
F15SMTD采用了带反推装置的二元推力矢量发动机
  下面的问题来了,推力矢量这么好,为啥美国的F15,F16不做改装,而让俄罗斯人拔了头筹?

  理由很简单,不是原始设计的改装重量代价太大,F16MATV推力矢量验证机,尾部增加了200公斤重量,为了平衡,机头也增加了200公斤,最终不堪重负,取消完事。

  另外一个理由就是,F16原始设计没有考虑推力矢量,所以飞机机翼机身设计都明显笨重,采用推力矢量后,要达到最优,就要对飞机到处动手术,机翼减小,平尾垂尾要减小,后机身要加长加强,这么一套下来,这飞机也不剩啥了,代价太大,得不偿失。

  推力矢量提高机动性效果还是很明显的,尤其是格斗,美国的X31技术验证机,采用简单的3挡板推力矢量技术,和F18近距离格斗,取得了8:1的绝对优势。

HHKb-fysuuyc0826104.jpg
就是这么简陋的3块挡板推力矢量,格斗时直接把F18战斗机吃的死死的
  现在世界各国战斗机从速度流,转向敏捷性,其中一个主要的思路就是机头指向必须快,机头指向快,可以更快把导弹射出去,而提高机头指向性的最好办法就是推力矢量,毕竟发动机推力大,尾喷管位置特别靠后,偏转形成的推力矢量力矩也大,在俯仰方向偏8-10度几乎等于舵面偏20-30的效果,而且效果更快捷。

  飞机采用推力矢量后,很多特性都会有改善,由于超环量使得飞机升力增加阻力减小,特别是低速时候更明显,由于飞机总阻力减小,航程会增加,推力矢量使得飞机的持续转弯速度和瞬时转弯速度增加,大大改善了飞机的敏捷性,使用推力矢量使得飞机滑跑距离明显减小。

pHmm-fysuuyc0826130.jpg
歼20战斗机,机翼面积和垂尾面积偏小,这个是考虑了推力矢量的结果
  歼20战斗机改装推力矢量涡扇15发动机之后,估计超音速巡航和机动性会有更好的表现,超音速巡航1.6马赫,超音速机动5g以上不掉速度,完全和F22持平。

  另外还可以优化隐身操纵模式,在不需要大机动的场合,可以减小鸭翼和襟翼舵面的偏转角度甚至不要动,保持最佳隐身气动外形,让发动机喷口上下左右微动即可,提高隐身性能。

  到了这个时候,横扫F35,干挺F22不一定是梦想。(作者署名:大水)

Syrian forces attacking eastern Ghouta ‘have surrounded rebels in Douma’
Largest town in region reported to be cut off as government forces press their advantage

Syrian government forces have surrounded the largest town in the besieged enclave of eastern Ghouta, in a prelude to a possible ground assault that could further inflame a dire humanitarian crisis.

Forces loyal to Bashar al-Assad have essentially split off Douma from the rest of eastern Ghouta, according to the Syrian Observatory for Human Rights, a day after a Red Cross and UN aid convoy arrived in the town to unload food supplies to thousands of civilians in desperate need. Douma was once one of the largest cities in Syria.

The report from the UK-based human rights group, which said both Douma and the smaller nearby town of Harasta were surrounded and cut off, was disputed by locals, but such an outcome seems inevitable in any event as the regime presses its advantage, backed by both Syrian and Russian airstrikes.

It also raises greater humanitarian concerns and fears for the lives of civilians living in the area, who have fled the government’s advance.

More than 1,000 people have been killed in the last two weeks of violence in eastern Ghouta, which borders the capital Damascus, according to Médecins sans Frontières, which has gathered data from hospitals in the area that it supports.

Q&A
How bad is the situation in eastern Ghouta and is aid getting in?
Local doctors said that between 49 and 65 people had died on Friday, and the near-ceaseless shelling that started on 19 February resumed on Saturday morning. Accurate figures for the dead are impossible to collate because many bodies remain trapped under the rubble of destroyed homes, and others are buried without being taken to hospitals.

The violence has continued despite a UN security council resolution demanding a 30-day ceasefire and the delivery of humanitarian aid “without delay”. Residents have spent weeks living underground in bomb shelters, suffering food shortages and a lack of medical supplies, with doctors saying they are overwhelmed by the number of wounded.

Reports of chemical attacks that may have involved chlorine or organophosphorus have also emerged in recent days, despite warnings by western powers that use of chemical weapons might prompt them to intervene in the unfolding crisis.

The UN secretary general has described the situation in eastern Ghouta as “hell on earth” and the body’s high commissioner for human rights described the military offensive as a “monstrous annihilation”.

The bombardment and encirclement of Douma continued even as rebels in the enclave, which is home to at least 300,000 people, acceded to a key demand by Russia: the evacuation of a few hundred al-Qaida-linked fighters in the enclave.

In a statement on Twitter on Friday, Jaish al-Islam, one of the main factions in eastern Ghouta, said the decision had been taken in consultation with the UN, a number of international parties and civil society representatives from eastern Ghouta. A few fighters were evacuated in an initial batch.

Jaish al-Islam and Faylaq al-Rahman, two Islamist rebel groups, control most of the opposition-held areas of eastern Ghouta. Any solution to the crisis will probably involve a partial evacuation of rebel fighters and perhaps civilians, in a deal similar to past surrender agreements between the government and rebels.

Moscow had justified the continued bombardment of the area by saying extremists remained embedded in the towns and were preventing civilians from taking advantage of a designated evacuation corridor to flee the fighting.

Q&A
Which outside powers are involved in the Syrian war?
Residents say they fear government retribution if they were to try and flee the area, or the possibility of being redrafted into the Syrian military and sent to fight on the frontline.

“If I thought about leaving Ghouta I would worry about the regime because there are no guarantees: and, second, I would worry about Jaish al-Islam, because they won’t let us leave,” said one activist in Douma. “If 100 families leave Ghouta, the regime will say they’ve evacuated all the civilians and then burn it all.

“We have no guarantees that the regime will protect the families that want to leave and that it won’t send the men to the frontlines,” he added.

Since you’re here …
… we have a small favour to ask. More people are reading the Guardian than ever but advertising revenues across the media are falling fast. And unlike many news organisations, we haven’t put up a paywall – we want to keep our journalism as open as we can. So you can see why we need to ask for your help. The Guardian’s independent, investigative journalism takes a lot of time, money and hard work to produce. But we do it because we believe our perspective matters – because it might well be your perspective, too.

I appreciate there not being a paywall: it is more democratic for the media to be available for all and not a commodity to be purchased by a few. I’m happy to make a contribution so others with less means still have access to information. Thomasine, Sweden
