Indonesian rescuers are battling strong currents on Friday as they resume the search for 30 people still missing at sea about 35 hours after a ferry sank killing at least six people, officials said.
The ferry named KMP Tunu Pratama Jaya was carrying 65 people, all Indonesians, when it sank about 30 minutes after setting sail from East Java bound for the holiday island of Bali on Wednesday night, said search and rescue agency official Ribut Eko Suyatno.
Twenty-nine survivors were rescued on Thursday before the search was called off due to poor visibility.
Rescue operations resumed on Friday in the waters of Bali Strait involving ships, helicopters, and hundreds of rescuers, Eko said. Strong currents and rain are expected.
Transportation safety investigators would probe the cause of the sinking when the search is over, officials said. The ferry was not overloaded when it went down, officials said on Thursday.
