Russia complains to Lithuania about its arms supply to Ukraine

VILNIUS (Reuters) - Russia said on Friday it had formally complained to Lithuania that the Baltic country's supply of weapons to Ukraine violated its international arms trade commitments.

Lithuania, Latvia and Estonia - part of the Soviet Union for much of the last century - worry that Russia's annexation of Crimea and support for rebels in Ukraine may be a foretaste of it reasserting itself in other former Soviet territories.
