The bodies of the Azerbaijanis were sent for a new forensic examination from Yekaterinburg to Baku, Seyfaddin Huseynli, the brother of the deceased Ziyaddin and Huseyn Safarov, said.
According to the Russian side, the two men were suspects in a case involving several murders and attempted murders committed years ago in Yekaterinburg.
The bodies were transported from Yekaterinburg to Azerbaijan's capital on a Ural Airlines flight. They will be re-examined in Baku before being released to relatives for burial in Aghjabadi on July 1.
On June 27, Russian security forces carried out an operation in Yekaterinburg as part of a criminal investigation into a 2001 murder case. Two people died during the operation. The methods used by the security personnel have caused bewilderment among both the public and officials in Baku.
The Yekaterinburg operation was connected to the investigation of an unsolved crime committed in 2001 - the murder of Yunis Pashayev, an Azerbaijani-born merchant. The crime remained unsolved at the time, and the case was eventually archived until being reopened recently. One theory suggests the security forces' unprecedentedly brutal actions may have been provoked by reasons not directly related to the criminal case.
