The United States and Iran said Monday they had exchanged strikes, further straining an already fragile cease-fire as negotiations between the two countries remain stalled.
Weeks of complicated talks marked by sharp rhetoric and occasional flare-ups of violence have not managed to reach a deal to end the war and reopen the Strait of Hormuz, which is essential to oil supplies.
Washington and Tehran have sharp differences on questions like Iranian nuclear efforts and the fighting in Lebanon, which Iran has demanded must stop as part of a broader agreement.
The latest exchange of fire coincided with Israel's expansion of its Lebanon invasion, with Prime Minister Netanyahu vowing to push deeper into the country.
The U.S. military announced that it had carried out "self-defense strikes" on Iranian radar and drone control sites in the southern part of the country over the weekend – its third such wave in just over a week.
