U.S. drone enters Iran's airspace, leaves after warning

Iran's military detected a U.S. drone entering Iranian airspace on Monday and issued a warning for it to leave, which it subsequently did, Reuters reported citing Iran's Tasnim news agency.

"Iran's army air defense detected and warned an American drone in the eastern airspace of the country. It was coming from Afghanistan. The drone left the area," Tasnim quoted the Iranian military as saying.

Tasnim gave no details on how the Iranian authorities had warned the unmanned drone to leave its airspace.
