The Kyrgyz National Security Service believes that militants from the Islamic Movement of Uzbekistan might have been involved in attempted terrorist attacks on the anti- terrorist coalition base in the Bishkek airport, Service Chairman Kalyk Imankulov said on Thursday. \"The National Security Service believes that the Islamic Movement of Uzbekistan might have been involved in attempts to commit terrorist attacks at the Gansi airbase at Manas International Airport near Bishkek,\" he said. Former airbase commander Steven Kelly said recently that Kyrgyzstan and the airbase security service had prevented no less than three terrorist attacks. Imankulov said there were extremist groups in Kyrgyzstan and one of them tried to carry out an act of terror at the airbase. He said that the attackers were arrested and that there is indirect evidence that they were linked to the Islamic Movement of Uzbekistan. Three Kyrgyz citizens were convicted for trying to organize a terrorist attack at the airbase in September 2003. The National Security Service has also indicted six Kyrgyz citizens for espionage, Imankulov said.
