Indonesian rescuers are continuing the search for 28 people still missing after a ferry caught fire off Madura island, an official said.

The death toll from an Indonesian ship that capsized rose to 66, as divers braved leaking fuel and dangerously unsound structures.

Beneath the surface of the Java Sea, fast currents, water pressure and hull design of a capsized ferry have hampered attempts to reach it.
