A 16-minute video posted by Facebook user Dahlia SenSasi shows dense grey smoke billowing from the unit into the corridor and to the flats above. Bright, orange flames could be seen inside the unit, as firefighters arrive at the scene. SCDF said that two fire engines, a Red Rhino, two fire bikes, an ambulance and three support vehicles were dispatched to the scene. The fire involved contents in the flat's living room, kitchen and two bedrooms, SCDF added. Firefighters put out the flames using two water jets. Two men in their 20s, who live in the unit, evacuated before SCDF's arrival. They were taken to Khoo Teck Puat Hospital for smoke inhalation. Investigations into the cause of fire are ongoing.
