At least eight were killed in Israel after Iran's latest missile barrage, according to Magen David Adom, an organization that provides emergency medical services across Israel. That brings the total number of deaths to 22 since the conflict started three days ago.

The Times of Israel, while quoting state media, also said on Monday that a third IRGC intelligence officer, Mohsen Bagheri, was also killed in the strike in Tehran.

The intensifying conflict has heightened fears of a protracted all-out war and widespread instability in the region.
