KIEV, July 8 - Two of Ukraine's largest banks - Privatbank and state-owned Oschadbank - have asked Moscow to compensate them for losses resulting from Russia's annexation of the Crimea peninsula from Ukraine last year, Reuters reported on Wednesday.

Already under pressure from an economic crisis in Ukraine, banks with significant assets in Crimea faced substantial writedowns after Russia seized the territory in March 2014 in a move condemned by Ukraine and the West.
