Russia vows retaliation after U.S. denies journalist visas.

The United States has denied visas to journalists who wanted to cover Russian Foreign Minister Sergey Lavrov’s trip to New York, prompting Lavrov to suggest that Moscow would take strong retaliatory measures. The journalists aimed to cover Lavrov’s appearance at the United Nations to mark Russia’s chairmanship of the Security Council. The dispute comes in the wake of high tensions with Washington over the arrest last month of Wall Street Journal reporter Evan Gershkovich, whom Russia accuses of espionage.
