A boat carrying more than 100 passengers is believed to have had an accident Saturday off the coast of Indonesia's Sulawesi after encountering rough seas and dispatching a distress signal, according to an official.
Transport ministry spokesman J.A. Barata said there were 118 people on board the passenger ferry, including 19 children and 10 crew, when it left Kolaka in southeast Sulawesi on Saturday morning.
Later in the afternoon, the vessel sent out a distress signal, claiming the ship "had an accident as a result of large waves 4 to 5 metres high", Barata said in a statement.
There was no mention of casualties, but Indonesia's search and rescue agency and navy have been notified.
A local search and rescue official told AFP authorities lost contact with the ship after it encountered high waves and strong winds.
However, there was no immediate indication if teams had been dispatched to the scene to locate the ferry's passengers.
The Indonesian archipelago of more than 17,000 islands is heavily dependent on ferry services but the industry has a poor safety record and fatal accidents are common.
