The 204th fight-jet airbase of the Ukrainian Air Force, which has 49 aircraft in service, has sided with the government of the Autonomous Republic of Crimea, a local government representative told Interfax on Monday.

"Today the command of the 204th base in Belbek has announced it is taking the side of the Crimean people," he said, adding that the base is more than 800 strong.

"The Belbek airfield has 45 Mikoyan MiG-29 fighters and four L-39 trainer aircraft. Of them, only four fighters and one trainer are in good condition," the official said.

Thus, "the total number of the Ukrainian Armed Forces servicemen, who have sided with the Crimean people, has approached 6,000," the source said.
