Another deadly blast has struck the southern Russian city of Volgograd, killing at least 14 people and further highlighting Russia’s security challenges as it readies to host the Winter Olympics in less than six weeks.
Like Sunday’s attack, the blast Monday was a terrorist act, Vladmir Markin, a spokesman for the country’s federal investigation agency, told the state-run news agency RIA Novosti.
No one claimed responsibility for the explosions. But they come several months after the leader of a Chechen separatist group pledged violence to disrupt the 2014 Sochi Winter Olympics. . .
