A Chinese fishing vessel ran aground the Tubbataha Reef late Monday, officials said, only days after the wreckage of a U.S. ship that hit the protected marine park had been removed.
The vessel, which carried 12 people believed to be illegal fishermen, hit the reef before midnight, staff at the Tubbataha Management Office said via phone.

Philippine Coast Guard Spokesperson Commander Armand Balilio, in a separate phone interview, said the vessel hit Tubbataha at around 1.1 nautical miles from the park ranger station.
The vessel remains in its grounding position as of press time, he added.
"If it can be moved from its grounding position come high tide, it will be escorted by BRP Romblon to Puerto Princesa," Balilio said.
He added that the passengers suspected to be poachers will be investigated for illegal entry.

The incident comes only about three months after United States minesweeper USS Guardian hit Tubbataha, damaging at least 2,345 square meters of the reef.
Salvage teams had to cut the warship into pieces so it could be removed without further damaging the UNESCO-protected site. The last parts have been lifted only on March 29.
The U.S. Navy has meanwhile relieved the warship's commander and three others for alleged failure to adhere to standard navigation procedures.
The Philippines is asking the U.S. to pay $1.4 million (P58 million) in compensation for the damage its warship caused on Tubbataha.
