U.S. intelligence officials will meet with congressional lawmakers about North Korea's alleged nuclear cooperation with Syria Thursday on Capitol Hill.

High-ranking U.S. officials are telling reporters the lawmakers will be shown video of North Koreans working at a suspected nuclear reactor site in Syria. The video also reportedly shows the reactor's design was identical to the North Korean reactor at Yongbyon.

The suspected reactor site was destroyed by Israeli warplanes last September. Damascus protested the air raid, accusing Israel of aggression. Both Syria and North Korea have denied the allegation.

The briefings are taking place as the Bush administration is trying to reach a deal with Pyongyang to end its nuclear weapons program.

North Korea agreed with Washington and four other nations (South Korea, Russia, Japan and China) to scrap its nuclear program in exchange for aid and some diplomatic benefits.

The isolated nation was supposed to make a full disclosure of its activities as part of the deal last December, but the U.S. says the list was incomplete.
