At least 22 people, including two guards, were killed when a riot broke out late on Wednesday in a prison in Tajikistan’s northern city of Khujand, sources close to local authorities told RFE/RL on Thursday (November 8). Several people were wounded in the fighting, sources said. It is still not clear what sparked the riot, which was quashed only after additional police forces were sent to the site. Security sources told RFE/RL that the fighting began after an inmate attacked and killed a prison guard. The body of one of the guards killed in the incident, 29-year-old Ehson Yoqubov, was buried in his native village of Pastighav on November 8, the village’s head Shohkarim Muhammadiev told RFE/RL. There was no immediate official reaction from the government. The local administration only confirmed that there had been a riot, without offering further information. The sources told RFE/RL that security forces were on high alert and that Justice Ministry staff and other officials flew to Khujand immediately after the incident last night. The sources spoke on condition of anonymity because they were not authorized to speak to the media on the issue. Tajik independent news agency Asia Plus cited sources at the Khujand city hospital as saying that six police officers were admitted to hospital with gunshot wounds. A doctor described their condition as "relatively serious," but "not life-threatening." Local residents say that police cordoned all roads and highways connecting Khujand, Tajikistan’s second largest city, with neighboring Uzbekistan and Kyrgyzstan.
