An office tower being built by Vietnam’s state power company caught fire Thursday, engulfing part of downtown Hanoi in black smoke. Official media said 30 workers were rescued, but it was not immediately clear whether others remained trapped inside.
Several workers waved their shirts from an upper-floor balcony to call for help after smoke began to engulf the building. Others used cellphones and flashlights to summon help.
Police sealed off the building and declined to comment. The fire appeared to be out by mid-evening, several hours after it started, but fire engines and ambulances still crowded the area.
