DUBAI, July 17 (Reuters) - The United States escalated its renewed bombing campaign on Iran on Friday by hitting bridges and an airport, and Tehran responded with strikes on U.S. bases across the Middle East.
In the contested Strait of Hormuz, where the renewed conflict has again cut off global energy supplies from the Middle East, U.S. Marines boarded a tanker and another ship was reported to have been hit by a projectile.
