MANILA, Philippines -- The United States deployed two warships on Wednesday in a disputed South China Sea shoal, where two Chinese navy and coast guard ships collided two days ago while trying to drive away a smaller Philippine ship in a high-seas accident captured on video, alarming several Western and Asian countries.

MANILA >> The Philippines expressed serious concern today over what it called “dangerous manoeuvres and unlawful interference” by Chinese vessels during a coast guard supply mission for Filipino fishermen in the Scarborough Shoal in the South China Sea.

The Philippines coastguard claims that a fighter tailed one of its aircraft and performed manoeuvres at close proximity.
