Sharjah24 – AFP: At least nine people died and an unknown number are missing after a passenger boat collided with a cargo vessel on a river in northwest Madagascar, authorities said on Monday.

Children were among the 35 people aboard the eight-metre (26-feet) boat when the collision occurred on Sunday evening on the Loza river near Antsohihy, the River and Maritime Port Agency (APMF) said.

Some passengers managed to swim ashore but others are unaccounted for.

"We don't know yet what happened to the other passengers," APMF Director-General Jean-Edmond Randrianantenaina said.

Rescue operations are still underway, he said.

The passenger boat was sailing from Ambiky when it was rammed by a cargo dhow and sank immediately, the agency said.

Randrianantenaina suggested the accident may have been caused by lack of lighting on the passenger boat.
