DUBAI, United Arab Emirates (AP) — Iran hit a tanker off the coast of Qatar and Kuwait International Airport early Wednesday as Tehran remained unrelenting in its attacks on its Gulf Arab neighbors, while acknowledging for the first time that Washington had been in direct contact about a possible ceasefire.

Israel sounded warnings of incoming fire from both Yemen and Iran, while launching its own attacks in Lebanon that killed at least five people.

An airstrike on Tehran appeared to have hit the former U.S. Embassy compound, which has been controlled by Iran’s Revolutionary Guard since the 1979 hostage crisis. Witnesses said buildings outside the massive compound had their windows blown out and that it appears the strike happened inside the walled facility.
