Iran launches missiles at central and north Israel as the Israeli military carries out further strikes in Iran.

Israel has issued an "urgent warning to Iranian citizens" to evacuate areas close to military sites after fresh exchanges of strikes between the two countries overnight raised fears of further escalation.

The region braced for a protracted conflict after Israel’s surprise bombardment of Iran’s nuclear and military sites on Friday killed several top generals and nuclear scientists, and neither side showed any sign of backing down.

Maj. Gen. Yadlin, who flew in the 1981 Osirak reactor strike, explains why Israel's current operation against Iran represents a complex, multi-week campaign.

Israel and Iran bombarded each other for a third day, with international concern growing that the conflict will spread across one of the world’s key oil-producing regions.

The strikes are a sign of Israel’s shift away from restraint, containment and short wars, and toward using force to project power across the Middle East.
