Meanwhile, investigators continued to search for clues and suspects in the 30 July suicide bombings outside the U.S. and Israeli Embassies and inside the Uzbek Prosecutor-General's Office. Three embassy guards and the three suicide bombers were killed, and eight other people were injured.
A team of Israeli experts arrived in Tashkent today to help in the investigation.
Uzbek authorities are blaming members of the banned Islamic group Hizb ut-Tahrir for the attacks.
Today the head of the group's London office, Imran Waheed, denied any involvement.
"We believe the people of Uzbekistan and Central Asia know very well what Hizb ut-Tahrir is, that it doesn't engage in violence or armed struggle, that it is an Islamic intellectual and political entity that is working to reestablish the Islamic caliphate. This attempt by [Uzbek President Islam] Karimov is just very much an attempt to malign the party and to associate it with violence and terrorism."
Several Islamic groups have claimed responsibility for the attacks.
