Israel on Sunday struck southern Lebanon, Beirut and an oil storage facility in Tehran as the war in the Middle East keeps escalating, and Prime Minister Benjamin Netanyahu promised “many surprises” for the next phase of the conflict.

Iran also hit a desalination plant in Bahrain. Earlier Sunday, Iran’s Foreign Minister Abbas Araghchi said a U.S. airstrike damaged an Iranian desalination plant on Qeshm Island, warning that in doing so “the U.S. set this precedent, not Iran.” Such infrastructure is critical for drinking water supplies in the parched deserts of the Gulf.

An Israeli attack on an oil storage facility in Tehran sent up pillars of fire that could be seen in Associated Press video as a glow against the Saturday night sky. It appeared to be the first time a civil industrial facility has been targeted in the war.

The war, which erupted on Feb. 28 after joint U.S.-Israeli strikes hit Iran, has so far killed at least 1,230 people in the Islamic Republic, more than 300 in Lebanon and around a dozen in Israel, according to officials.

Major developments we’re following:

Iranian president apologizes for attacks: Iranian President Masoud Pezeshkian apologized Saturday for attacks on “neighboring countries,” even as his country’s missiles and drones flew toward Gulf Arab states and hard-liners asserted that Tehran’s war strategy would not change. Pezeshkian’s message underlined the limited powers exercised by the theocracy’s leaders over the paramilitary Revolutionary Guard, which controls the hundreds of ballistic missiles targeting Israel and other countries.Evidence suggests the deadly blast at an Iranian elementary school was likely a U.S. airstrike. The Feb. 28 strike produced the highest reported civilian death toll since the war began, prompting staunch criticism from the United Nations and human rights monitors. The U.S. has not accepted responsibility but said it was investigating the matter.The death toll continues to rise. At least 1,230 people in Iran, more than 300 in Lebanon and around a dozen in Israel have been killed, according to officials in those countries.
