The U.S. State Department has called for an internationally-backed investigation into last week's deadly clashes in the Uzbek city of Andijan.
State Department spokesman Richard Boucher says Washington is deeply concerned over what he called reports of "indiscriminate" firing by Uzbek authorities on demonstrators.
Uzbek officials took foreign diplomats Wednesday on a tour of Andijan, the scene of last Friday's clashes between anti-government demonstrators and security forces.
But some of the diplomats complained they were not allowed to roam freely and could meet only selected residents who backed the government's version of events.
One opposition group estimates that 745 people were killed, while the government says 169 died, including 32 soldiers. The Uzbek government says many of the dead were killed by Islamic extremists.
