U.S. President Trump declares ceasefire with Iran "over" after renewed hostilities, including U.S. airstrikes and Iranian attacks on commercial vessels and U.S. military infrastructure.

The U.S. and Iran have engaged in a sharp escalation of tit-for-tat strikes, with the U.S. military hitting at least 170 targets in Iran and Iran responding with attacks on commercial vessels in the Strait of Hormuz and U.S. military infrastructure in Gulf states. President Trump stated the ceasefire, agreed upon in mid-June, is now "over," though the U.S. has agreed to Iran's request to continue talks. This escalation has raised concerns about global oil supplies and shipping through the critical Strait of Hormuz.
