Haitians still waiting for aid

The Haitian authorities say they have buried 40,000 bodies so far and believe another 100,000 could be dead in the rubble.

In the capital Port-au-Prince many bodies still lie in the open, the injured remain untreated, and the frustration of survivors grows.

International agencies are struggling to deliver aid to hundreds of thousands of earthquake survivors in Haiti.

Huge volumes of aid have been promised - and the United States is to send extra troops, as well a hospital ship.

Efforts are concentrating in the capital Port-au-Prince but the chronic lack of infrastructure is causing major problems with distribution.
