Suicide bombers have struck the U.S. and Israeli embassies and the state prosecutor's office in the Uzbek capital, Tashkent, killing at least two people and wounding at least nine others.
Those killed, in addition to the bombers, are reported to be Uzbek citizens who were working at the embassies.
The attacks came as 15 suspects stand trial this week for a wave of violence in Uzbekistan earlier this year that killed at least 47 people.
The Prosecutor General's office says it has opened a criminal investigation into Friday's attacks.
Uzbek President Islam Karimov has cut short a visit to Ukraine's Crimean peninsula to return home.
