The United States has deployed two warships to the disputed South China Sea near Scarborough Shoal. This follows a collision between Chinese navy and coast guard ships while they attempted to drive away a smaller Philippine vessel.

Footage shows a Chinese coast guard vessel chasing a Philippine boat and then ramming a Chinese warship. It was the latest confrontation in the contested waters.

Philippine authorities said Monday's accidental collision resulted in visibly heavy damages to the Chinese coast guard and navy ships and possible injuries.
