Col. Noel Detoyato, Armed Forces of the Philippines (AFP) public affairs office chief, said, “All afloat vessels in the Western Command area have already been mobilized to conduct assessment, retrieve the aground vessel and return her to safe harbor, and assist all personnel aboard BRP Del Pilar.”

Other assets from nearby AFP installations are also on standby for any contingency, he added.

Initial reports showed that none of the personnel on board have been hurt due to the incident.

"An investigation is expected in such situations to find out the possible causes of the grounding and to come up with steps to ensure that similar incidents will be prevented," Detoyato added. (PNA)
