Eleven fishermen from two trawlers were reported missing, said disaster official Do Son in central Quang Ngai province. Six fishermen from another boat were initially reported missing after their vessel sank Friday while seeking shelter at the Paracel islands off Vietnam's coast.

In the northern province of Quang Ninh, authorities found a man who was earlier reported missing after his small boat sank in the picturesque tourist attraction of Ha Long Bay, said disaster official Pham Dinh Hoa.
Authorities also recovered the body of a 1-year-old who died of an illness just before the storm hit. The body was swept away from the mother when the small boat she was using to ferry the body for burial capsized, he said.
Authorities also found the body of a female Vietnamese tourist swept away by big waves while swimming, said disaster official Nguyen Thi Bich Lien, in northern Thanh Hoa province. The woman was not counted as a victim because she drown before the storm came.
