A fire in a nine-story apartment building in Vietnam’s capital killed about 12 people and injured more than 50. State media reported the fire has been extinguished and rescue operations were continuing Wednesday. Authorities have not confirmed an exact death toll. Rescuers struggled to reach the building on a narrow lane in south Hanoi, and it wasn’t immediately clear how much of the building had burned. It was home to 150 residents, and 54 of the 70 people rescued from the fire were hospitalized for their injuries. Authorities were investigating the cause of the fire.
