Russian President Vladmir Putin has asked 755 US diplomats to leave the country. The action was taken three days after the US Congress approved sanctions against Russia. Earlier, the US Senate approved a bill to toughen sanctions on Russia for allegedly meddling in the 2016 US Presidential election and for its annexation of Crimea in 2014. Putin in an interview to a Russian TV channel said, more than 1000 people are working at the US embassy and consulates in Russia. He said 755 of them should stop their activities and return.
