JAKARTA, July 24 (Xinhua) -- Indonesian search and rescue authorities on Friday suspended an operation for 14 people still missing after the KM Nurul Salsa passenger boat sank off South Sulawesi province.

The National Search and Rescue Agency said the operation was temporarily closed after a 10-day search yielded no new leads, despite all designated search areas being thoroughly covered.

Of the 76 people confirmed to have been on board, 58 were rescued, four were found dead and 14 remained unaccounted for, according to the agency.

The agency said evacuation efforts would be launched if new information emerged indicating that any of the missing victims had been located.

The vessel sank after suffering engine failure in waters off South Sulawesi on July 15 while travelling from Jampea Island to Benteng.
