Pro-Russian militants presented a captured team of international observers as "prisoners of war" in Ukraine on Sunday, adding fuel to the crisis as US President Barack Obama warned Moscow against "provocation".
Obama said Russia had "not lifted a finger" to implement a peace deal struck in Geneva on April 17 to ease the crisis. He added that Moscow faced "consequences, and those consequences will continue to grow".
Obama and his Western allies are planning a new round of sanctions against Moscow that could be introduced as early as Monday.
The escalating crisis saw Moscow last week order new military exercises on the border of Ukraine and warn of "consequences" after Kiev launched a deadly assault against pro-Kremlin rebels occupying a flashpoint town.
There are fears Moscow is planning to take over more Russian-speaking parts of Ukraine in a similar way to that which saw it absorb Crimea last month.
