KABUL (Reuters) – A Black Hawk helicopter crashed during a Taliban training exercise in Afghanistan’s capital Kabul, killing three, the group’s defence ministry said. “An American Black Hawk helicopter, which was flown ... for training, crashed due to a technical problem inside the campus of the National Defense University,” said Ministry of Defense spokesperson Enaytullah Khowrazmi, adding five people also were injured. The Taliban took control of some U.S.-made aircraft after they seized power in 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.
