TEHRAN, Iran (AP) — Iran’s defense minister said Friday that a U.S. drone violated Iranian airspace a week ago when Pentagon says the pilotless aircraft came under fire. The U.S. maintains the drone was over international waters.

“Last week, an unknown aircraft entered Iran’s airspace in the Persian Gulf,” said Gen. Ahmad Vahidi. “It was forced to leave on time by a wise and strong reaction on the part of the Iranian armed forces.”
