Russia briefly detains, deports US broadcasting chief

The Broadcasting Board of Governors said in a statement that its chairman, Jeff Shell, was denied entry into Russia on arriving at Moscow's main international airport late Tuesday despite having a valid U.S. passport and Russian visa.

The State Department said it had expressed concern about what happened to Russian officials but declined to comment further pending a complete review of the incident.

[...] the expulsion of the U.S. broadcasting executive also takes place amid a spike in other tensions between the United States and Russia, including a tit-for-tat expulsion of diplomats from both nations last week related to an altercation between an American diplomat and a Russian security guard outside the U.S. Embassy in Moscow.
