Thirteen Filipinos were rescued from a South Korean cargo vessel that flipped on its side off the coast of Georgia, the United States Coast Guard (USCG) said as rescue workers freed the final crew member trapped inside.

In a statement, the USCG said along with the 13 Filipinos, the rescued included six South Koreans and the American pilot, the foreign ministry earlier said as salvage crews gradually drilled an opening in the ship’s massive hull on Monday.

It was done to first deliver food and water to the survivors, then to extract them, the US Coast Guard added.

The last missing crew member emerged from the hole at around 6 a.m. Tuesday in Manila and was able to stand on the hull of the ship as rescue workers helped him, a USCG Twitter video showed.

It noted that the final crew member had been trapped behind a glass panel in the ship’s engineering control room and was the only one of the four who did not get any food and water when rescuers broke through the hull around 35 hours into their ordeal.
