DUBAI—Iran has been urgently signaling that it seeks an end to hostilities and resumption of talks over its nuclear programs, sending messages to Israel and the U.S. via Arab intermediaries, Middle Eastern and European officials said.

Iran is not winning this war, and they should talk, and they should talk immediately before it's too late,' Trump said at the G7 Summit in Canada.

Smoke and missiles have lit up the skies in Israel and Iran in a fierce standoff triggered by fears over Tehran’s expanding nuclear program. Since June 13, hundreds of military strikes have been exchanged as the two nations remain locked in a conflict that shows no signs of abating.
