The United States expanded its airstrike campaign against Iran early Friday by hitting more bridges, electrical equipment and collapsing a tower at a key Iranian port, part of U.S. President Donald Trump's threats to start striking infrastructure to pressure Tehran to ease its chokehold on the Strait of Hormuz. Iran launched new missile attacks against U.S.-allied nations in the Middle East, including Qatar, a key mediator in the war.

The interim ceasefire agreed to last month has collapsed, and the region has endured days of back-and-forth attacks by the U.S. and Iran as they battle for control of the strait. Iranian officials say U.S. strikes have killed dozens of people and wounded hundreds of others, with new casualties reported in Friday's strikes.

Deadly U.S. strikes overnight hit an airport, a railway station in the port city of Bandar Abbas and two bridges in southern Iran near the Strait of Hormuz, Iranian state media said Friday.

The U.S. State Department said Wednesday it has approved the sale of an estimated $1.96 billion in weapons to bolster Saudi Arabia's air defenses, as the war ramps up in the Middle East.

Pakistan said on Thursday it would encourage the United States and Iran to stop violence and resume talks under a memorandum of understanding (MoU) it helped mediate last month.

A drone struck a ship located off the port in Iraq's southern province of Basra on Thursday, a security official told AFP.

Tehran warned Thursday it would target regional infrastructure if the United States carried out threats to attack Iran's infrastructure, as the war in the Middle East resumed.

The spokesman for Iran's military headquarters said that if the U.S. followed through on its threats, "all infrastructure in the region" would be "crushed under the steel blows" of Iran's armed forces.

More than half the House Democrats voted Wednesday to strip $3.3 billion in U.S. aid from Israel, the most substantial signal yet that once rock-solid bipartisan support for the country is disintegrating in the aftermath of its war in Gaza that has killed thousands of Palestinians.

The vote tally, 104-314, was not enough to attach the amendment to a broader national security spending bill, but stands as a stark accounting of the shifting attitudes that are dividing the Democratic Party and the nation over Israeli Prime Minister Benjamin Netanyahu's war strategy, now approaching its third year.

The United States intensified its strikes targeting Iran early Thursday, hitting targets further north as American forces also fired into a ship it accused of trying to break its naval blockade on the Islamic Republic. Iran retaliated with missile and drone fire targeting Bahrain, Jordan and Kuwait before dawn and warned its attacks may escalate.

Days of back-and-forth strikes by the U.S. and Iran across the Middle East — and renewed threats to the Strait of Hormuz — have shredded the interim deal to end the Iran war and could tip the region back into all-out war. Already, Iranian officials say U.S. strikes have killed more than 35 people and wounded over 300 others.

The Gulf monarchies of Kuwait and Bahrain on Wednesday confirmed they had intercepted fresh aerial salvos from Iran as Tehran and Washington exchanged fire over control of the vital Strait of Hormuz.

The Israeli military said on Wednesday it had sentenced an active-duty soldier to five years in prison for sending videos of missile interceptions to an Iranian agent.

The soldier sent two such videos during the 12-day war with Iran in June last year and "received payment for them," the military said. It added that he had also shared several videos filmed in civilian locations with the Iranian agent.
