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 fired a new wave of missile attacks on Israel early Monday, triggering air raid sirens across the country as emergency services reported at least five killed and dozens more wounded in the fourth day of a conflict between the regional foes that showed no sign of slowing.

It follows daytime attacks from both sides, with Israeli strikes in Tehran continuing and Iran firing more missiles towards Israel.
