Barack Obama Among 500 Americans Banned From Russia In Retaliation For US Sanctions

Russia said it banned entry to 500 Americans, including former president Barack Obama, in response to sanctions imposed by Washington. 

Russia's foreign ministry, in a statement, said that the move comes after US refusal last month to give visas to media traveling with Foreign Minister Sergei Lavrov to the United Nations.
 
"Washington should have learned a long time ago that not a single hostile attack on Russia will go unpunished," the statement by Russia's foreign ministry added.
