A packed ferry boat has capsized in heavy winds and rain in remote north-eastern India, leaving at least 35 people dead and 75 others feared missing.

Assam state police chief JN Choudhury said the boat was carrying about 200 passengers, but details were sketchy because bad weather and the remoteness of the area hampered communication.

He said the accident occurred on the Brahmaputra river near Fakiragram in west Dhubri district. The area is about 215 miles west of the state capital, Gauhati.

Mr Choudhury said strong winds and rain probably caused the accident.

Police and paramilitary soldiers have been sent to help with rescue efforts.
