(QHA) -

Ukraine's acting President Oleksandr Turchynov has called for the relaunch of an "anti-terrorist" operation against pro-Russian rebels in eastern Ukraine, citing the death of a politician from his party in the region, RFE/RL reports.

Turchynov said in a statement that two "brutally tortured" bodies were found near the rebel-held city of Slovyansk on April 22.

One was that of Volodymyr Rybak, a member of Turchynov's Batkivshchyna (Fatherland) party. The president said Rybak had recently been abducted by "terrorists."

Turchynov said, "These crimes are being carried out with the full support and indulgence" of Russia.

In his statement, Turchynov said, "I call on the security agencies to relaunch and carry out effective antiterrorist measures, with the aim of protecting Ukrainian citizens in the east from terrorism."

To recall, Ukraine's acting President Olexander Turchynov has announced the start of an "anti-terrorist operation" against pro-Russian separatists April 13.
