Ukraine mourns the death of a prominent Russian opposition figure, who Ukrainian President Petro Poroshenko says had evidence of Russian links to the Ukraine conflict. Nathan Frandino reports.
Outside the heavily guarded Russian embassy in Kiev, a sign of respect lies in peace. This sign here reads Ukraine mourns, as residents pay tribute to Russian opposition politician Boris Nemtsov. Nemtsov was killed on Friday in Moscow. He is hailed by Ukrainian President Petro Poroshenko as a bridge between the two countries. (SOUNDBITE) (Ukrainian) UKRAINIAN PRESIDENT, PETRO POROSHENKO, SAYING: "Boris Nemtsov was killed. He was a great friend of Ukraine and a great patriot of Russia. He was a person who, like a bridge, connected Ukraine and Russia and who built those relations between Ukraine and Russia, which I would like to see." His murder showed the risks of speaking out against Russian President Vladimir Putin, who has promised to find and punish the killers. Poroshenko, meanwhile, says Nemtsov's murder was directly related to the crisis in eastern Ukraine. (SOUNDBITE) (Ukrainian) UKRAINIAN PRESIDENT, PETRO POROSHENKO, SAYING: "Boris declared that he would reveal persuasive evidence about the involvement of Russian armed forces in Ukraine. Someone was very afraid of this. Boris was not afraid. The hangmen and executioners were afraid. They killed him." Kiev and the west say Moscow is funding and arming pro-Russian rebels. Moscow denies this, as well as any involvement in Nemtsov's death.
