DHAKA, Bangladesh — A Bangladesh Air Force training aircraft crashed into a school campus in the capital, Dhaka, shortly after takeoff on Monday, killing at least 18 people including the pilot and injuring 164 others, the military said.

According to the military and a fire official, the Chinese-made F-7 BGI aircraft crashed into the campus of Milestone School and College, in the Uttara neighborhood, in the afternoon as students were attending classes.

The military said the jet took off at 1:06 p.m. local time and crashed soon after, catching fire immediately. The cause was not immediately clear.

It is the deadliest airplane crash in the Bangladeshi capital in recent memory.

Local media indicated most of the injured were students. Relatives panicked at the scene as rescuers, using tricycle rickshaws or whatever was available, transported the injured to local hospitals.

Rafiqa Taha, a student who was not present at the time of the crash, told The Associated Press by phone that the school, with some 2,000 students, offers classes from elementary to twelfth grade.

“I was terrified watching videos on TV,” the 16-year-old said. “My God! It’s my school.”
