Rescuers were searching for 17 missing fishermen after two boats collided in waters off Indramayu, in West Java province, officials said Sunday.

A fishing ship hit a larger cargo vessel on Saturday evening off Indramayu regency, flipping the wooden boat's 32 crew members into the water, said Bandung rescue agency spokeswoman Seni Wulandari.

"Some 15 survivors have been evacuated to the cargo vessel but the team is still searching for 17 other crew who went missing," Seni told AFP on Sunday.

Those rescued sustained minor injuries from the accident and would be taken to a nearby hospital, she added.

The Habco Pioneer cargo vessel was sailing through the port of Merak from the Indonesian island of Borneo when it was hit by a local fishing boat in Indramayu waters, said Seni.

Boat accidents are common in Indonesia, a Southeast Asian archipelago of around 17,000 islands, due to lax safety standards.

In January last year, 10 people went missing after a boat carrying 20 migrant workers to neighbouring Malaysia capsized off the coast of Sumatra island.
