Russia vs. United States

Russia named 18 Americans banned from entering the country in response to Washington imposing sanctions on 18 Russians for alleged human rights violations.

The move came a day after the United States announced its sanctions under the Magnitsky Law, named for Russian lawyer Sergei Magnitsky, who was arrested in 2008 for tax evasion after accusing Russian police officials of stealing 230 (m) million US dollars in tax rebates.

He died in prison the next year, allegedly after being beaten and denied medical treatment.
