More Marines heading to Middle East as U.S. continues relentless strikes on Iran

Around 2,500 U.S. Marines are heading for the Middle East, along with a Navy amphibious warship. Their mission is not yet clear, but it signals a marked increase in U.S. forces in the region. The deployment comes as the Pentagon said more than 15,000 targets had been struck in Iran over nearly two weeks of relentless bombing against the regime. Stephanie Sy reports.
