White House spokeswoman Dana Perino says the United States provided "specific support" in the Colombian hostage rescue operation that freed Colombian politician Ingrid Betancourt and three Americans.

"We were aware of the operation in its planning stages," Perino said during Thursday's briefing. "We provided some specific support, which I'm not allowed to go into the details on, but President Bush was certainly supportive of it."

Perino said the U.S. has been working with Colombia to help free the hostages since they were taken in 2003, but gave credit for the successful operation to Colombian President Alvaro Uribe.

"What I can tell you is that the whole world now saw who is responsible for releasing the hostages, and that was President Uribe, who deserves all of the credit," Perino said, again saying that the U.S. "certainly supported the operation and provided some specific support."
