Former U.S. Attorney General Ramsey Clark and an American Roman Catholic bishop vowed Saturday to push for an end to U.N. trade sanctions on Iraq.

They made the pledge as 80 American aid workers handed over $4 million worth of medicine, vitamins and medical supplies to Iraqi health authorities."We have come in defiance of our own government. We do not feel any people can be forced to ask permission of a genocidal power," Clark said at a news conference.

Such visits to Iraq by Americans technically violate U.N. Security Council sanctions imposed on Iraq after its 1990 invasion of Kuwait unless permission is sought.

Clark, U.S. attorney general under President Lyndon Johnson and founder of the humanitarian group International Action Center, said he will continue ferrying relief supplies to Baghdad "as long as they are needed."

He also promised to lobby hard against the sanctions until an end is put to "the murderous conduct of our own government."
