A ferry has capsized off Haiti's southern coast, killing at least six people. Dozens are missing.

Civil protection official Jean-Michel Sabbat says the boat overturned Saturday morning en route from Anse a Pitre, near the Dominican border, to the southern peninsula city of Jacmel.

Sixteen survivors have been rescued and crews are still searching. Sabbat says rough estimates put as many as 60 people aboard the vessel.

Officials could not immediately say what kind of boat it was, or what caused it to overturn.
