A portrait of Russian police senior sergeant Dmitry Makovkin, who was killed in a suicide bomb blast at the city's main railway station, is displayed at a funeral service in Volgograd, January 2, 2014. The suicide bomb blast at Volgograd's main railway station on Sunday afternoon killed at least 18 people. The suspected involvement of converts to Islam in Russian suicide bombings points to the growing reach of jihadists far beyond the Muslim provinces of Chechnya and Dagestan, where insurgency and separatism have simmered for two decades. Russian news media say the authorities suspect an ethnic-Russian convert to Islam may have been behind the first of two suicide bombings that killed a total of 34 people in the past two days in Volgograd, a southern Russian city.
