A passenger ferry carrying more than 50 people is sinking in waters between the Indonesian islands of Bali and Java.

Muhammad Arifin, head of the East Java's search and rescue agency, says Friday that more than 50 people have been rescued.

But he doesn't know if all on board are accounted for. He says the agency is trying to obtain the ferry's manifest.

MetroTV showed the ferry on its side in calm waters in Bali Strait.

The ship was enroute from Gilimanuk port in Bali to Banyawangi on Java.
