DUBAI, United Arab Emirates (AP) — The U.S. military launched airstrikes Sunday targeting Iran’s paramilitary Revolutionary Guard to retaliate for the killing of American troops in Jordan, further widening the crossfire between the nations as they fight over Strait of Hormuz.

The strikes, now part of a weeklong campaign that has seen Iran strike U.S.-allied countries across the Middle East, comes as an interim deal seeking to find an end to the Iran war has collapsed.
