Vice President Joe Biden says Russia must uphold its end of a truce in east Ukraine in order to resolve the conflict which has claimed at least 4,300 lives since March.

Biden met with Ukrainian President Petro Poroshenko Friday, exactly one year after protests kicked off in November 2013 that would eventually help oust the country's pro-Russian ex-president from power.

Biden said that Russia was violating a September cease-fire agreement meant to bring stability to east Ukraine, where pro-Russian rebels are fighting Kiev's troops. He warned that Russia, which has been hit with Western sanctions, could expect "rising cost and greater isolation" in response to its actions.
