Russia's Deputy FM Sergei Ryabkov said on state TV that Washington had been informed in the last days that Moscow will see weapons supply convoys entering Ukraine as "legitimate targets". 

"We warned the United States that the orchestrated pumping of weapons from a number of countries is not just a dangerous move, it is a move that turns these convoys into legitimate targets," Ryabkov said in the remarks, which served as a severe warning to the West.
