Iran’s military threatened to attack all energy infrastructure linked to the US and Israel in the Middle East if its power plants are targeted, after Trump threatened new attacks. The Iranian military announced intercepting a US-Israeli armed drone in the skies over Tehran before it could carry out any combat operations, according to the Tasnim news agency. The Islamic Revolutionary Guard Corps (IRGC) claimed on Saturday its air defences shot down an Israeli fighter in Iranian airspace, the third such incident reported during the war. Israel did not confirm this. Iran’s Atomic Energy Organisation said Israel and the US targeted the country’s Natanz nuclear site on Saturday in “criminal attacks”. Tehran also informed the International Atomic Energy Agency (IAEA) about the attack, which confirmed no unusual radiation leak. Iran’s President Masoud Pezeshkian called on the BRICS alliance, currently chaired by India, to “play an independent role in halting aggressions against Iran”. He also proposed establishing a regional security framework of West Asian countries. Iran’s state broadcaster noted the death toll from the US-Israeli attacks has now topped 1,500, according to the Ministry of Health, and at least 20,984 people were injured, with seven hospitals evacuated and 36 ambulances damaged.
