The Philippine military released video of what it said was a nearly hour-long attack off Second Thomas Shoal in the contested South China Sea, where Chinese ships have unleashed water cannon and collided with Filipino vessels in similar stand-offs in recent months.

China Coast Guard and other vessels “once again harassed, blocked, deployed water cannons, and executed dangerous manoeuvres” against a routine rotation and resupply mission to the shoal Saturday morning, the National Task Force for the West Philippine Sea said.
