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.

Four days into their war with Iran, Israelis are shaken and anxious, yet remain resilient, still backing Prime Minister Benjamin Netanyahu's decision to confront a longstanding foe.

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.
