"This aspect worries not only Russia, but also the U.S., which has its own sources of information and is seriously concerned about the involvement of a whole number of international terrorist organizations in the attempt to destabilize the situation in the south of Uzbekistan," Foreign Ministry's official spokesman Alexander Yakovenko said.
He particularly pointed to the statement by the U.S. State Department that members of extremist organization, such as the Islamic Movement of Uzbekistan, Islamic Jihad, Al Qaeda and Eastern Turkestan, remain proactive in the region.
"Russia has insisted on thorough investigation into the events in Andizhan, which are still unclear from the viewpoint of external forces' involvement in destabilizing the situation in the region," the spokesman said.
On May 13 Uzbekistan's fourth largest city, Andizhan, witnessed an armed seizure of a jail and a number of administration buildings. The Uzbek police stormed and liberated the buildings. A hundred and seventy-three people were officially reported killed, however, journalists and human right activists insist on hundreds of dead.
