A mission by the flagship of the US Sixth Fleet, the USS Mount Whitney, marks the end of the US military's role in delivering relief supplies to Georgia, a Pentagon spokesman said Monday.

Pentagon spokesman Bryan Whitman said the US military will turn next to assessing Georgia's security needs in the aftermath of a Russian invasion last month, but he said it was too soon to say when the first security assessment teams will go in.

The Mount Whitney unloaded 17 tons of relief supplies over the weekend, the last of three US warships to deliver aid to Georgia.

"I would say with the completion of the Whitney's mission we have come largely to the end of the DoD (Department of Defense) relief efforts unless there are new requirements that are identified to us," he said.

"The next step for us will be at some point down the road to send in a security assessment team to look at what their needs might be with respect to that," he said.

Russia's military surged into Georgia on August 8 to rebuff a Georgian offensive to retake the Moscow-backed separatist region of South Ossetia.
