A day ahead of a NATO summit, Russian President Vladimir Putin issued his own peace plan for eastern Ukraine, calling on the Russian-backed insurgents there to "stop advancing" and urging Ukraine to withdraw its troops from the region. Hours earlier, Ukraine had issued a vague statement about agreeing with Putin on cease-fire steps. The separatists rejected the move, saying no cease-fire was possible without a pullback by Ukraine, while Putin's spokesman claimed that Moscow could not agree to a cease-fire because it was not a party to the conflict.
