Aerial attacks between Israel and Iran continued overnight into Monday, marking a fourth day of strikes following Israel's Friday attack. That surprise strike hit the heart of Iran's nuclear program, killing several nuclear scientists as well as high-ranking military leaders, according to Israeli officials.

Israel bombarded Tehran, the Iranian capital, with a new wave of strikes on Sunday afternoon, as both sides dismissed international calls to de-escalate the conflict and warned of more to come in a clash that is rapidly expanding in scope and intensity.
