U.S. and Philippine navy ships have patrolled waters in the southern Philippines where kidnappings by ransom-seeking Abu Sayyaf militants have sparked a regional security alarm. U.S. Navy Lt. Cmdr. Arlo Abrahamson said a Navy combat ship, the USS Coronado, and the Philippine Navy frigate BRP Ramon Alcaraz completed the four-day patrol at the Sulu Sea on Saturday, July 1, 2017, adding that the operation was carried out at the request of the Philippine government.
