Armed pro-Russian separatists seized more buildings in eastern Ukraine on Monday, expanding their control after
the government failed to follow through on threatened military crackdown
leaving Moscow 's
partisans essentially unopposed.
European
foreign ministers agreed to widen sanctions against Moscow
and the White House said Washington was
seeking ways to impose more "costs" on Russia ,
for what Kiev and its Western friends call a
Russian plot to dismember Ukraine .
