DUBAI, United Arab Emirates - 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 exchange of fire between them as an interim deal seeking an end to their war has collapsed.
The strikes are part of a weeklong campaign that began with a struggle over control of the Strait of Hormuz and has seen Iran strike U.S.-allied countries across the Middle East.
