The source also mentioned that several warning shots and two warning missiles had been fired from Sirik and the nearby Karpan area towards vessels violating its Hormuz regulations hours earlier. However, Iran's Mehr news agency later quoted the head of ports at eastern Hormozgan as stating there was no damage to the port of Sirik, with facilities operating normally.US secretary of state Marco Rubio and Israel's ambassador to the US Yechiel Leiter applaud after signing a framework agreement between Israel and Lebanon with State Department counsellor Daniel Holler and Lebanon's ambassador Nada Hamadeh in Washington on 26 June 2026 (Reuters)Iran's Revolutionary Guards asserted that their navy "struck the locations where the terrorist US military is stationed in the region" in response to the new strikes.
