A Russian engineer Sergey Gorbunov was executed by the Islamic State (IS) terrorist organization, The New York Post reported.

"Sergey Gorbunov was dragged out of his cell and shot to death this past spring," the newspaper said.

The last video with the Russian engineer was published by the extremists in October 2013. "They treat me well, give food, but if in five days I'm not exchanged for Khalid Suleiman from Saudi Arabia... then I will be killed. I appeal to the President of Syria, Russia, to the Red Cross ... I am very afraid," Gorbunov said in the video.

The jihadi group has already released a number of videos showing the execution of foreign citizens. Among the IS victims are American reporter James Foley, American-Israeli journalist Steven Sotloff and British aid worker Alan Henning.
