June 1 (UPI) -- The United States and Iran said they traded attacks late Sunday, with each side claiming to have hit military targets, the latest tit-for-tat strikes amid a brittling cease-fire.

U.S. Central Command said in a statement that it attacked Iranian radar and command and control sites in Goruk, on the Iranian mainland, and Qeshm Island, in the Strait of Hormuz, on Saturday and Sunday.

It said the "measured and deliberate strikes" were in response to "aggressive Iranian actions," including the shootdown of a U.S. drone operating in international waters.

"U.S. fighter aircraft swiftly responded by eliminating Iranian air defenses, a ground control station and two one-way attack drones that posed clear threats to ships transiting regional waters," it said.
