The warning came on the fourth day of the conflict, when the Israeli military claimed it had achieved air superiority over the Iranian capital and could fly over the city without facing major threats.

Iran unleashed a barrage of missile strikes on Israeli cities early Monday, after Israel struck military targets deep inside Iran, with both sides threatening further devastation. AFP images showed gutted residential buildings in Tel Aviv and fires smouldering outside the coastal city of Haifa,

The barrage of missiles fired between Israel and Iran continued into a fourth day, with Israel saying it hit an Iranian command center, while Iran hit populated areas of Israel, killing at least eight people.
