Five Filipino seafarers were reported missing after their Taiwanese fishing vessel caught fire off the Falkland Islands. The Philippine Department of Foreign Affairs (DFA) said in a statement that the country’s embassy in London was trying to get more information about the incident.

The five Filipinos were among 69 crew members of a Taiwanese fishing vessel and have reportedly been missing since Monday after their vessel caught fire.

“The embassy is closely coordinating with relevant authorities and the manning agency of the Filipino seafarers and is ready to provide assistance,” the DFA said.

The DFA said it remained hopeful that the Filipino seafarers would be found.

According to the Falkland Islands government, the vessel, identified as the Jung Ron, had caught fire about 60 nautical miles north of Stanley, the islands’ capital.

The 64 other crew members were rescued and arrived in Montevideo on Friday. The cause of the fire is yet to be known.

A quarter of the world’s ship crew members are Filipinos, making the Philippines the biggest source of mariners. More than 20% of the world’s 1.2 million sailors are manning oil tankers, luxury liners, and passenger and fishing vessels worldwide, exposing them to piracy attacks and sea accidents.
