"In terms of U.S. assistance, we made an initial contribution at the beginning of this effort of 30 million dollars in humanitarian relief. About 23 million dollars of that is already, in effect, on the ground. That takes the form of both badly needed medical supplies, cash contributions to the International Committee of the Red Cross," Casey said.

Moreover, Casey said that U.S. Secretary of State Condoleezza Rice had announced another 20 million dollars as help to Lebanon and the United States will be an active participant in the international donors conference expected on Aug. 31.

"Obviously we want to see everybody in the international community do what they can to meet both the short and long-term needs of the Lebanese people here. And I believe we have more than425 million dollars in aid that's already been pledged, including the U.S. contributions, by the international community to date," Casey said.
