Manila said Monday that Chinese vessels "intentionally hit" Philippine boats at the weekend, escalating a diplomatic row over two collisions in the South China Sea.
The countries have traded blame over Sunday's incidents near Second Thomas Shoal in the Spratly Islands, with both sides filing diplomatic protests and releasing videos to support their accusations.
The two collisions happened during a Philippine resupply mission to troops stationed on a navy vessel that was grounded on the shoal in 1999 to assert Manila's territorial claims.
