MOSCOW, December 15. /TASS/. Observers from the US diplomatic mission will not be allowed at polling stations during the Russian presidential election next year in March based on the principle of reciprocity, Russian Deputy Foreign Minister Sergey Ryabkov said on Friday.

"We have sent a note to our US colleagues saying that considering their refusal to grant access to our observers from Russian diplomatic missions in the United States to US presidential elections, we will be guided in this issue by the principle of reciprocity," the Russian diplomat said.
