Two deputy commanders at the Iranian armed forces' general staff were killed in Israeli attacks, Iranian state media reported on Saturday. It was unclear when the two commanders were killed but their deaths were announced on Saturday.

Israel's attacks on Iran since Friday have killed at least 78 people, including senior military officials, in what are Israel's biggest attacks ever against Iran.

Iran also launched attacks against Israel as retaliation. Citing senior Iranian military officials, Iran's Fars News Agency reported on Saturday that Iran's strikes against Israel will continue, with targets set to expand to include U.S. bases in the region in the coming days.

"This confrontation will not end with last night's limited actions and Iran's strikes will continue, and this action will be very painful and regrettable for the aggressors," Fars reported, citing senior military officials.

They were quoted saying that the war would "spread in the coming days to all areas occupied by this (Israeli) regime and American bases in the region."
