Russian opposition politician Boris Nemtsov, who was shot dead in February 2015, was killed with a homemade firearm assembled using imported parts, Russia's Federal Security Service (FSB) said.
"Such weapons are used by underground gang members and organized criminal groups to commit serious and high-profile crimes: a series of killings of Moscow region residents by the so-called GTA gang in 2014, the killings of public figure Boris Nemtsov and member of the local government of Chereksky district in the Kabardino-Balkar Republic Kantemirov in 2015," Sputnik cited the FSB as saying.
The security service noted an increase inflow of illicit supply of weight-size mock-ups from abroad to Russia, mostly from Ukraine. Such mock-ups can be turned into combat weapon in a handicraft way, the FSB said.
