"We are still awaiting further developments on the latest Somali piracy case," Noli de Castro said in a statement that named the seized vessel as the African Sanderling, which has a crew of 21 Filipinos.
The Malaysia-based watchdog International Maritime Bureau reported on Wednesday that the bulk carrier was boarded by armed men in the Gulf of Aden while en route to Asia from the Middle East.
"I want to reiterate our appeal to the international shipping companies to take extra precautionary measures and to strictly follow the directive to limit voyages to the 'safe zone' or the Maritime Security Patrol Area," de Castro said.
"Multinational naval forces of US, Britain, and France among others, are patrolling and giving assistance to vessels" using this corridor, he added.
