There have been no known direct talks between the two sides since April 11, and escalating tit-for-tat strikes threaten a return to all-out conflict.

Any renewed attacks would follow strikes by both the U.S. and Iran following the downing of a U.S. helicopter.

The U.S. military said it struck Iranian sites at the direction of President Donald Trump after two helicopter crew members were rescued by a Navy sea drone — a first for the U.S. military, officials said.

Central Command called the attack "a proportional response to unjustified Iranian aggression." The military did not elaborate on what targets were struck.

The ⁠United States, Australia, ⁠European allies and other countries ​condemned Iran-backed groups' plots to ‌kill Iranian dissidents, journalists ‌and Jewish communities ⁠in ⁠a joint statement released on Wednesday.

Nevertheless, the United States must, of necessity, respond to this attack,” Trump wrote in a post on Truth Social at 12:34 p.m. It was not immediately clear what the U.S. response would actually entail,

Israel struck the historic port city of Tyre in southern Lebanon on ⁠Tuesday ⁠killing at least eight people, the Lebanese health ministry ⁠said, and minutes later ordered the evacuation of the entire city for the first time.

President Donald Trump had urged restraint after the two countries intensified attacks, and Iran said it would halt its strikes.
