An ethnic Tatar man in Russia's Tatarstan region has been sentenced to six years and three months in a maximum security prison for killing an ethnic Russian doctor.
The Chally City Court found Misbakh Sakhabutdinov, 86, guilty of premeditated murder on April 21 and sentenced him the same day.
Sakhabutdinov pleaded guilty to killing Andrei Zheleznov with a homemade firearm concealed in his walking stick.
Sakhabetdinov's relatives told RFE/RL that several years ago, when the elderly man came to Zheleznov's clinic with a severely cut finger, the doctor ordered him to put off his tubetei, a traditional Tatar hat.
When Sakhabetdinov refused and said he could not due to his Islamic faith, Zheleznov refused to treat him and security guards forced him out of the clinic.
According to Sakhabetdinov's relatives, the old man was deeply offended and decided to seek revenge.
