Russia: NATO involvement in Ukraine threatens 'unpredictable' escalation
Feb 7 (Reuters) - Russia's defence minister said on Tuesday that Western arms supplies to Ukraine were effectively dragging NATO into the conflict, warning this could lead to an "unpredictable" escalation.
"The U.S. and its allies are trying to prolong the conflict as much as possible," Defence Minister Sergei Shoigu said in a conference call with military officials.
