One team, from the Israel Defense Forces, began setting up a surgical field level hospital at an abandoned athletic field.
"They're the first ones who are going to be operating," Furin said.
The Israeli delegation of 220 arrived at the Antoine Izmery soccer field Friday to begin setting up tents and equipment. Its doctors and other medical personnel anticipated treating about 500 casualties a day. Much of the aid will be focused on helping any survivors of the destroyed U.N. headquarters in the capital, Port-au-Prince.
