HANOI—A Vietnamese military helicopter crashed on the outskirts of Hanoi on Monday morning, killing 16 military personnel and injuring five others, a senior military official said.
"The accident happened in Thach That (an outlying district of Hanoi) when the MI-171 helicopter was conducting a parachuting exercise," Vo Van Tuan, the deputy chief of staff of the Vietnamese People's Army, told The Wall Street Journal.
Thach That is about 19 miles (35 kilometers) from the center of Hanoi.
The aircraft crashed onto an abandoned house in the district and no civilians were killed or hurt, an official in the district said on condition of anonymity.
State media reported the helicopter crashed shortly after it took off from Hoa Lac Airport near Hanoi around 7:30 a.m. Monday.
Authorities rushed the injured to a nearby hospital and cordoned off the crash site for investigation, online news provider VnExpress reported.
