Although the evacuation operation is not over, Pentagon spokesman Bryan Whitman told a press briefing that "we are coming close to completing the assisted departure operations. We are going to be shifting our emphasis to a humanitarian effort."

Whitman said the U.S. military has evacuated 11,913 Americans from Lebanon since July 16 and is expecting another 1,200 out of that country Monday.

U.S. navy vessels are not likely to evacuate any more people from the country, he said.

Meanwhile, two U.S. navy ships are ready to deliver humanitarian relief supplies to Lebanon, among them are medical kits, blankets and other humanitarian aid provided by the U.S. Agency for International Development.

Nongovernmental organizations will then distribute the supplies to those who need them.

The medical kits are large enough to provide supplies for 10,000 people for three months, Whitman said.

He said U.S. military personnel will be on hand when the supplies land, but that will probably be the extent of U.S. military involvement in Lebanon.
