Iran's Islamic Republic of Iran Broadcasting (IRIB) reported explosions in the Sirik area of southwest Iran after multiple shells struck a communications tower. US media Axios, citing US officials, said the U.S. military is striking Iranian targets in the Strait of Hormuz region in response to Iran's Saturday attack on a commercial tanker. Axios said this is the second round of U.S. airstrikes since the signing of a U.S.-Iran memorandum of understanding.

Israeli Army Radio reported the Israeli military will reduce forces stationed in southern Lebanon and withdraw several combat brigades.

Politico reports that after U.S. and Israeli strikes on Iran on Feb. 28, Israeli officials briefly viewed the alliance as entering a 'golden era' but four months later are preparing for greater isolation. U.S. Vice President Vance told Israel last week it 'has almost no friends' and warned it not to attack its only remaining powerful ally. Seven sources, including U.S. and Israeli officials, said Vance's remarks reflect a new normal in which Israel's status no longer receives priority treatment from Washington. Tensions are visible: one source said Prime Minister Netanyahu visited Washington five times in 2025 but has made only one trip this year, in February, and phone contact has fallen sharply.
