MOSCOW, April 14 (Xinhua) -- The U.S. military's recent use of the largest non-nuclear bomb in Afghanistan poses a threat to incite a new round of arms race, a Russian senator said Friday.

"The U.S. test of the new bomb in Afghanistan is an attempt to establish the world dominance with an element of a military threat which may initiate a new round of arms race and increase tension in the world," Igor Morozov, a member of the Federation Council's Foreign Affairs Committee, was quoted by RIA news agency as saying.

Russia should initiate a discussion about the incident at the United Nations (UN) Security Council, he said.

On Thursday, U.S. forces in Afghanistan dropped a GBU-43, or Massive Ordnance Air Blast (MOAB) bomb, to strike an Islamic State (IS) target.

This is the first time that the U.S. military used a MOAB bomb, nicknamed "the mother of all bombs," in combat.
