The Russians arrived in Tajikistan: They are conducting interrogation

Three Tajik security sources told Reuters that Russian investigators were questioning the families of suspects in the Crocus City Hall attack in Moscow, which killed 139 people and injured around 180.

The sources, who were not authorized to provide information on the case, said that Tajik security officials brought the families of the suspects from different parts of the country to the capital Dushanbe.

The four attackers have been indicted in Russia, where they face life imprisonment for the terrorist attack.
