Black Hawk helicopter crashed during a Taliban training exercise in Afghanistan’s capital Kabul, killing three, the group’s defence ministry said on Saturday.

“An American Black Hawk helicopter, which was for training, crashed due to a technical problem inside the campus of the National Defence University,” said Ministry of Defence spokesperson Enaytullah Khowrazmi, adding five people were also injured.

The Taliban took control of some U.S.-made aircraft after they seized the country just over a year ago.

It remains unclear how many are operational. U.S. forces deliberately damaged some military hardware as they left and Afghan forces had flown some helicopters to central Asian nations.
