US Iran war news LIVE: Mohsen Rezaei, an adviser to Iran's Supreme Leader Mojtaba Khamenei, accused the US of violating the memorandum aimed at ending the war by creating tensions in the Strait of Hormuz.
Tehran said on Saturday that it had struck targets linked to US forces in response to American airstrikes on its southern coast, as both sides accused each other of violating last week's agreement aimed at ending the four-month-old war.
Iran's foreign ministry did not disclose the locations of the "defensive" strikes, saying they were carried out in response to what it described as "the barbaric air strikes" by the US on its coastal surveillance facilities.
Tehran also alleged that the American attacks violated the UN Charter, according to a Reuters report.
Later, Bahrain, which hosts the US Navy's Fifth Fleet, condemned what it said was an Iranian drone attack on its territory, calling it a flagrant violation of its sovereignty and a threat to its security.
The Gulf nation added that it reserved the right to defend itself.
