The Philippine Coast Guard on Friday accused its Chinese counterpart of blocking efforts to evacuate a sick member of its armed forces in the South China Sea, calling its actions "barbaric and inhumane."

The incident, which the Philippines said took place last month, involved a member of a small contingent of marines posted to guard the BRP Sierra Madre, a Philippine vessel grounded at the disputed Second Thomas Shoal, the site of repeated confrontations with China this past year.

Coast guard spokesperson Jay Tarriela said coast guard and navy boats were harassed by Chinese vessels, despite having informed them the operation was of a medical nature.
