Invasion possible

Poland’s foreign minister Radoslaw Sikorski told the TVN24 BIS television channel that a renewed buildup of Russian troops on Ukraine’s border may foreshadow an invasion. The troop buildup comes as President Vladimir Putin's response U.S. and European sanctions.

Russian army units gathering near the eastern Ukrainian regions of Donetsk and Luhansk, are poised to pressure or invade according to the minister and Poland is among the EU nations seeking the toughest response to Russia over Ukraine. Estonia also fears that Putin may be planning a military incursion.

Putin is showing no sign of backing down over Ukraine since the U.S. and the EU tightened sanctions last week. Russia, which annexed Crimea from Ukraine in March, has deployed 45,000 soldiers, 160 tanks and as many as 1,360 armored vehicles, a Ukrainian military spokesman, Andriy Lysenko, told reporters in Kiev today.
