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

In Israel, at least 10 people were killed in Iranian strikes overnight and into Sunday, according to the Magen David Adom rescue service, bringing the country’s total death toll to 14. The country’s main international airport and airspace remained closed for a third day.

Iranian Foreign Minister Abbas Araghchi said Sunday that if the Israeli strikes on Iran stop, then “our responses will also stop.”
