Ukrainian PM warns of default risk, calls for more Western help

KIEV (Reuters) - Ukraine risks defaulting on its debt unless Western donors come up with more funds on top of the billions of dollars of financial aid already promised, Prime Minister Arseny Yatseniuk said on Thursday.

A year of revolution and war with pro-Russian separatists has pushed Ukraine's hryvnia currency to record lows and crippled the economy, which was already near bankruptcy after years of corruption and economic mismanagement.
