These raids had a major impact in Central Asia, and resulted in considerable international pressure on Tajikistan, not least from Karimov, to expel the IMU from its base in the Tavildara Valley. The IRPT persuaded their former ally Namangani to abandon Tavildara in late 1999. Controversially, Namangani and his fighters were then flown from Tajikistan to northern Afghanistan in Russian military helicopters – a move which enraged Karimov, who claimed the Russians were aiding the IMU in an attempt to undermine Uzbekistan.
