The ​US military attacked Iran on Friday in response to an Iranian drone strike on a cargo ship in the Strait of Hormuz, further ‌straining the fragile peace deal agreed last week between the two countries, reported Reuters.

US Central Command said aircraft struck missile and drone storage locations and coastal radar sites. 

US President Donald Trump blamed the attack on Iran and said it violated last week's agreement.

Trump on Friday called Iran's attack a "foolish violation" of the ceasefire, as Tehran and Washington appear to remain at odds on even basic points in their memorandum of understanding, including control of the strait and how Iran will spend its unfrozen funds, reported CBS News.

"The unwarranted aggression against commercial shipping by Iranian forces clearly violated the ceasefire," ​US Central Command said in its statement announcing the strikes, which it called "a powerful response to yesterday’s attack on a commercial ship that was transiting the Strait of Hormuz."

The US military said it would continue to provide "safe passage coordination and support" to commercial vessels transiting the strait.

Vice President JD Vance said "violence will be met with violence" after the US retaliatory strikes against Iran, said the CBS News report.

"Iran signed a ceasefire agreement. We have honoured it. If they have disagreements about how the MoU is being applied, they can pick up the phone," Vance said on social media, referring to the memorandum of understanding between the two countries. "But violence will be met with violence."

The IRGC blamed the "treaty-breaking US regime for violating its commitments and launching an airstrike on the coast of the Islamic Republic of Iran under various pretexts of a ship violating an unauthorised route in the Strait of Hormuz," reported BBC.

"If the aggression is repeated our response will be more extensive than this," it warned.

Iranian state media, citing an unnamed military source, reported the strike at the port of Sirik after an explosion ​was heard there. The source said several warning shots had been fired from Sirik toward vessels that violated Strait of Hormuz regulations about five hours earlier, adding ​that two warning missiles had also been launched from the nearby Karpan area toward the strategic waterway.

CNN, citing an unnamed US official, reported the US operation had concluded.

Previously Iran had expressed anger at what it said was an "interventionist, irresponsible and provocative" statement by ‌the US and six Gulf states that rejected its assertion that it could charge tolls on vessels transiting the strait.

Elsewhere there were signs of progress, however, as Israel and Lebanon signed an agreement to ​end the fighting between Israel and Iran-backed Hezbollah. 

Both sides framed the deal as an initial step that calls for Hezbollah to disarm and Israel ​to withdraw troops from Lebanon, but it was not clear how it would be enforced. Hezbollah said it would not cooperate, said the Reuters report.

US Secretary of State Marco Rubio said the negotiators had taken an important step towards achieving peace between Lebanon and Israel, adding "There's a lot of work ahead. We don't in any way underestimate the difficulty of the task ahead, but we understand the importance of it. How vital it is, and we are honored to have played a part in bringing this together."

Lebanese Ambassador Nada Moawad and her Israeli counterpart Yechiel Leiter signed the trilateral document with the US at the State Department in Washington, providing few details.
