Russian Foreign Minister Sergei Lavrov said Monday Moscow will not militarily interfere in the ongoing Ukraine crisis, urging the United States and the European Union (EU) to help stop Kiev from using heavy weapons.

"There will be no military interference ... We advocate only peaceful settlement of the heaviest crisis, the tragedy," Lavrov said in a speech at the Moscow State Institute of International Relations.

Meanwhile, he accused the EU of exerting strong "sanctions inertia," referring to the bloc's Sunday decision to apply further sanctions on Russia within a week given Moscow "continues to escalate the Ukraine crisis."

Washington and Brussels, Lavrov said, should give up the "absolutely hopeless policy of ultimatums, threats and sanctions" if they want to resume pragmatic cooperation with Russia.
