Nearly one year after an earthquake devastated the Haitian capital Port-au-Prince, bodies are still being found under the rubble of collapsed buildings.

The gruesome discoveries highlight the pace of reconstruction in Port-au-Prince, where an estimated 1.5 million people are still homeless and even major landmarks such as the presidential palace and national cathedral show no sign of being rebuilt.

Only a few blocks from the palace, workers privately hired to clear debris from what used to be a restaurant stumbled upon the remains of a man, his skeleton caught under a collapsed wall for the last 12 months.

An Oxfam report released this week says only five per cent of the rubble produced by the earthquake has been removed over the past year, a fact attributed to lack of organisation and logistical co-ordination by non-profit organisations and the Haitian government.

The Haiti earthquake, which struck a year ago on Wednesday, has been described as the "biggest urban disaster" in modern history. An estimated 230,000 people were killed in the magnitude 7.0 earthquake with more than 1.5 million left homeless.

The Disasters Emergency Committee appeal for Haiti in the aftermath of the disaster prompted a huge response, raising £106 million. The umbrella organisation for 13 humanitarian aid agencies, said the money has helped 1.2 million survivors so far.

Ten months after the earthquake, the island suffered another blow when it was hit by a major outbreak of cholera.

British health charity Merlin said in a new report that international medical response teams staged a "takeover" after the devastating earthquake in Haiti, undermining the country's own ability to provide health care.

While local doctors and nurses were "welcome and vital", few of the foreign aid agencies made use of them and the extensive health facilities in Port-au-Prince after the disaster, international health charity Merlin said.

Having been at the forefront of saving lives in the initial aftermath, local health workers found themselves sidelined and undermined, Merlin said.
