Israel pounded Iran in a series of air raids on Friday, striking 100 targets including Tehran's nuclear and military sites, and killing the armed forces' chief of staff, the head of Iran's Revolutionary Guards and top nuclear scientists.
Iran's Supreme Leader Ayatollah Ali Khamenei warned Israel it faced a "bitter and painful" fate over the attack, which also killed a senior Guards commander according to Iranian media.
Iran had launched 100 drones in response towards Israel whose defences were working to intercept, the Israeli military said.
US President Donald Trump told Fox News he had advance notice of the Israeli strikes which Israel's military said involved 200 fighter jets.
