More than 160 people were injured after the training aircraft crashed because of a mechanical error, military officials said. The country’s interim leader called the loss “irreparable.”

At least 19 people were killed as a Bangladesh air force training aircraft crashed into a college and school campus in the capital city of Dhaka on Monday, a fire services official said.

A Piper PA-46 crashed into a field north of the airport shortly after taking off around 8 a.m., according to the FAA. The pilot was the airplane’s only passenger, the agency said.
