(Updates with two deaths reported)
MANILA, Aug 17 (Reuters) - A ferry sank after a collision with a domestic cargo vessel off the central island of Cebu in the Philippines on Friday night, and hundreds of people were rescued, local radio said.
The radio said two people had been killed. It was not clear if there were further casualties.
The ferry had left Cebu port for Manila with 692 crew and passengers when the collision occurred, said Rear Admiral Luis Tuazon. The cargo ship was helping to rescue passengers.
Hundreds of people were plucked from the waters by dozens of fishing boats that rushed to the area, the radio reports said. Many were brought to local hospitals. Coastguard authorities were investigating the accident. (Reporting by Manny Mogato, editing by Mark Trevelyan)
