US-Iran Tensions Surge: What Triggered the Latest Military Strikes?

US strikes Iran over Strait of Hormuz attack: CENTCOM

U.S. forces conducted strikes on Iran on Friday in response to the Iranian drone strike on a Singapore-flagged cargo ship in the Strait of Hormuz, according to U.S. Central Command.

"The unwarranted aggression against commercial shipping by Iranian forces clearly violated the ceasefire. Furthermore, Iran's dangerous behavior undermined freedom of navigation as commerce increasingly flows through the vital international trade corridor," CENTCOM said in a statement.

The U.S. on Friday targeted Iranian missile and drone storage locations as well as coastal radar sites, CENTCOM said.

The strikes are ongoing, according to a U.S. official.

The strikes were announced shortly after President Donald Trump told reporters in the Oval Office that "you're going to find out" if the U.S. will respond.

Trump on whether US will respond after Iranian drone strike: 'You're going to find out'

After President Donald Trump accused Iran of violating the ceasefire for shooting drones at ships in the Strait of Hormuz, he told reporters in the Oval Office that "you'll have to find out" when asked if Iran will face any consequences.

Asked by ABC News Senior Political Correspondent Rachel Scott if he considered the ceasefire to still be in place, Trump responded that he didn't "like the fact" that they shot four drones, one of which damaged a ship.

"They shouldn't be doing that. So you'll find out. I mean, you’ll find out exactly," he continued.

Asked if the U.S. will respond, Trump said, "You're going to find out."

Rubio says agreement a 'framework for lasting peace'

Secretary of State Rubio said the agreement reached Friday between Israel and Lebanon "begins to put in place a framework for lasting peace and security."

He thanked the people in the room for their work but acknowledged there was still a long road ahead of them.

"As I told all the parties here today, it's the beginning of the beginning. There's a lot of work ahead," Rubio said at the State Department. "We don't in any way underestimate the difficulty of the task ahead, but we understand the importance of it, how vital it is."

Rubio held calls with Israeli Prime Minister Benjamin Netanyahu and Lebanese President Joseph Aoun to get the framework agreement over the finish line and joined the talks in person Friday morning, according to a U.S. official.

The agreement is expected to include immediate action by both sides, including limited withdrawals from Israeli forces.

Despite the signing of the agreement, there is still no guarantee that Hezbollah will abide by its terms.
