A Russian businessman who set up a Josef Stalin museum in the city once named after the Soviet dictator has been beaten to death by attackers.
Vasily Bukhtienko was attacked by three men on a tennis court in Volgograd (formerly known as Stalingrad), in southern Russia, officials said
They say the men used electric shock devices and then repeatedly hit Mr Bukhtienko on the head.
He later died from his injuries. The motive for the attack is not known.
In 2005, Mr Bukhtienko founded a Stalin museum near an imposing monument commemorating the 1942-43 Battle of Stalingrad, which is considered by many historians as a turning point in World War II.
