The number of people missing after a typhoon devastated the Philippines has risen to nearly 900 after families and businesses reported losing contact with more than 300 fishermen at sea.
The fishermen from southern General Santos city and nearby Sarangani province left a few days before Typhoon Bopha hit the main southern island of Mindanao on Tuesday, civil defence chief Benito Ramos said.
The death toll has already passed 600, mostly from flash floods that wiped away precarious communities in the southern region unaccustomed to typhoons.
Mr Ramos said the fishermen were heading to the Spratly Islands in the South China Sea and to the Pacific Ocean. Coastguard, navy and fishing vessels are searching for them and some may have sought shelter on the many small islands in the area.
"Maybe they are still alive," Mr Ramos said.
Bopha was finally dissipating in the South China Sea after briefly veering back towards the country's north west on Saturday, prompting worries of more devastation.
Rescuers were searching for bodies or signs of life under tons of fallen trees and boulders in the worst-hit town of New Bataan, where rocks, mud and other rubble destroyed landmarks, making it doubly difficult to search places where houses once stood.
Nearly 400,000 people, mostly from Compostela Valley and nearby Davao Oriental province, have lost their homes and are crowded inside evacuation centres or staying with relatives.
President Benigno Aquino has declared a national calamity, which allows for price controls on basic commodities in typhoon-affected areas and the quick release of emergency funds.
Officials said 316 people were killed in Compostela Valley, including 165 in New Bataan, and 301 in Davao Oriental. More than 45 people were killed elsewhere. Nearly 900 are missing, including the fishermen and 440 from New Bataan alone.
