The incident comes days after two Chinese vessels collided, allegedly while pursuing a Philippine patrol ship in the vicinity of the contested Scarborough Shoal.

MANILA, Philippines — The U.S. deployed two warships Wednesday in a disputed South China Sea shoal where two Chinese ships collided earlier in the week while trying to drive away a smaller Philippine ship in a high-seas accident that raised alarms about maritime safety.

A Chinese jet fighter "intercepted" a Philippine aircraft carrying journalists during a patrol flight over the Scarborough Shoal on Wednesday, the Manila government said, days after two Chinese vessels collided in the area while allegedly trying to block a Philippine supply mission.
