WASHINGTON (AP) - The White House says the secret military documents released by the whistle-blower WikiLeaks reveal names, operations, logistics and sources involved in the U.S.-led war in Afghanistan.

White House spokesman Robert Gibbs says those revelations have the potential to do harm and their release is "alarming." But at the same time he says that most of the information is not new.

The Pentagon says it is trying to assess the damage caused by the leak of the 91,000 classified documents on the Afghanistan war.

The founder of wikileaks said this is just the beginning. His team is reviewing another 15,000 war documents before releasing them.
