North Korea will send 51 athletes and officials to the upcoming Winter Asian Games in February, games organizers said Tuesday.

North Korea's national Olympic committee faxed an official entry list to the organizing committee Tuesday morning -- more than two weeks past the official deadline and following repeated delays in completing official entry procedures.

The games will be held over eight days in Aomori Prefecture, beginning Feb. 1.

Pyongyang's announcement comes amid growing concerns over a nuclear crisis following its withdrawal last week from an international treaty intended to prevent the spread of nuclear weapons.
