A Vietnamese naval ship on Monday saved nine foreigners from a lifebuoy after their ship were attacked by pirates.
The foreigners - six Indonesians, two Malaysians and the captain from Myanmar - were crew members on Malaysian tug boat Atlantic 3 which was heading to Thailand.
Captain Myint Shwe said they were attacked on the night of April 27 with knives and handguns in the waters between Malaysia and the Philippines.
Shwe said the pirates took all their valuables including food and kept them until Sunday night when they pushed them on to the life buoy.
The Vietnamese ship was visiting soldiers on the Truong Sa (Spratly) Islands when they found the victims, who were rescued and transferred to another boat sailing to the mainland.
