Washington ? The Bush administration turned to the NATO military alliance Thursday for help transporting to the United States a burgeoning international inventory of relief equipment that has been offered to aid the victims of Hurricane Katrina.

Ninety-five countries have offered about $1 billion in cash and goods, as well as technical assistance, U.S. officials said. But some of the supplies remained abroad, where foreign officials in some instances said they have not heard back from U.S. counterparts on whether their offers will be accepted.

An offer of 20 million barrels of Iranian crude oil has been refused. Iran said it would provide oil if the United States dropped the economic sanctions that now bar U.S. companies from doing business with the country. U.S. officials said they wouldn’t accept an offer that was conditional.

The Cuban government has publicly offered the help of 1,000 physicians. U.S. officials have stopped short of refusing the aid, but have said they don’t need such help at the moment, because of the “robust” U.S. health care system.

The countries offering aid include a number of major recipients of U.S. aid. Among them are Afghanistan, which offered $100,000 cash; Iraq, which offered $1 million; and Israel, which offered tents, first-aid kits, milk, beds, food, and search and rescue teams.
