Magnitude 6.1 aftershock strikes Haiti
The U.S. Geological Survey said it had a magnitude of 6.1 and was centred 26 miles (42 km) west-northwest of Jacmel.
There was no immediate reports of damage from the quake, which struck after daybreak.
Haitian officials say the death toll from the January 12 magnitude 7 quake was likely to be between 100,000 and 200,000. Fearing new damage from aftershocks, thousands of people have been sleeping in streets in the capital Port-au-Prince since then.
