The success of its Haiti earthquake fundraising appeal has spurred international aid charity World Jewish Relief to step up the help it is providing to the stricken island.

Chief executive Paul Anticoni has launched an appeal for medical and health experts to form teams to run four mobile clinics.

The teams - a doctor and two primary health care nurses - will visit displacement camps housing thousands of refugees whose homes were destroyed.

Mr Anticoni said that Jewish doctors and nurses "must be prepared to spend at least six months in Haiti. We will also need a logistics co-ordinator, to organise supplies, transportation and the routes the clinics will follow, and an overall project co-ordinator."

He said that WJR would be working with international health care organisation Merlin, and that the doctors and nurses would be paid on their tour of duty out of the money from the Haiti appeal.
