A U.S. Navy destroyer sailed within 12 miles of the disputed Scarborough Shoal in the South China Sea on Monday in a challenge to China’s maritime territorial claims that will likely set off renewed Chinese complaints.

President Trump threatened to destroy Iran in a tweet sent in the wake of reports that a rocket was fired into Baghdad’s heavily fortified Green Zone less than a mile from the US Embassy.
