A major attack targeted the Asaluyeh gas facility in southwestern Iran.
The facility accounts for about half of Iran's petrochemical industry and is linked to a large offshore gas field in the Persian Gulf, which hosts the largest fossil gas reserves in the world, across an area of sea that has been divided between Iran and Qatar.
Monday's attack was "powerful," Israeli Defense Minister Israel Katz said, but state Iranian media said the damage was limited and no casualties were reported.
Israel bombed facilities in the same area a few weeks ago, causing further escalation, sending energy prices soaring and angering the United States. President Donald Trump said at the time that Israel would not attack the gas field again - but warned that he would bomb it completely if Iran did not stop attacking energy facilities on the Arabian Peninsula.
Bombed Tehran
Israel also reportedly attacked a petrochemical plant near the city of Marvdasht, near Shiraz, on Monday. According to the state-run Fars news agency, no one was injured in the attack, which caused "a minor fire."
Overnight, Israel also bombed Tehran and other parts of Iran, after which Iranian state media reported at least 25 deaths.
Iran's Revolutionary Guard announced that one of its leaders, intelligence chief Majid Khademi, was killed in a dawn attack, which Israel also reported.
Victims under rubble
Iran in turn attacked Israel. A rocket hit the port city of Haifa in northern Israel on Sunday. The remains of four victims were found in a collapsed seven-story building. In Tel Aviv, four people were injured by rockets.
Iran also attacked targets in the United Arab Emirates, Kuwait and Saudi Arabia.
Donald Trump threatened the Iranian regime with escalation in increasingly aggressive terms if it did not reopen the closed trade route through the Strait of Hormuz. In a post on Truth Social, Trump wrote that if the blockade was not lifted by Tuesday evening, the United States would "bomb Iran worse than ever before" and destroy civilian infrastructure such as power plants and bridges.
Iran's Revolutionary Guard, by contrast, announced that new measures to control the strait were underway. A military spokesman told AFP that Iran can "continue the war as long as the political leadership deems it necessary."
