Three prison guards and 29 inmates were killed in a prison riot in Tajikistan that the government blamed on Islamic State militants.

The militants then torched the prison hospital, took several inmates hostage and tried to fight their way out. Security forces killed 24 militants in the battle to restore order in the prison, the ministry said.

The prison houses 1,500 inmates, some of whom rights activists describe as political prisoners.

Among prisoners who were killed by militants were two senior members of the Islamic Renaissance Party of Tajikistan (IRPT), once an influential party represented in parliament and government, which was outlawed by the government of President Imomali Rakhmon in 2015, the ministry said.

Another victim was a prominent Tajik cleric convicted on charges of calls to overthrow the government.

The authorities said one of the instigators of the riot was Bekhruz Gulmurod, a son of Gulmurod Khalimov, a Tajik special forces colonel who defected to Islamic State in 2015 and, according to the government, has since been killed in Syria.

The ministry did not specify whether the 20-year-old younger Gulmurod – who was convicted in 2017 for trying to join his father in Syria – was among those killed in the riot.

The road to the prison was blocked by security forces on Monday who refused to let in reporters or dozens of inmates’ relatives who had come to check on them.

“We were told to leave and they said they would inform us about our relatives when possible,” said an elderly woman whose son was in the prison.

Hundreds of people from the impoverished former Soviet republic of 9 million are believed to have joined Islamic State, which at one point controlled large swathes of land in Syria and Iraq.

The group, which has now lost its strongholds but continues underground operations, claimed responsibility for another Tajik prison riot last November, which followed a deadly attack by its followers on Western tourists in Tajikistan in July 2018.
