Western heads of state say they are considering fresh sanctions against Russia over its alleged failure to help de-escalate the crisis in Ukraine.
France, Germany, the US, Britain and Italy accused Russia of disrespecting a deal to disarm pro-Russian separatists in eastern Ukraine.
Russia earlier accused the West of wanting to "seize" Ukraine.
