As officials in Moscow said that US diplomats would be ordered to leave in a tit-for-tat response, the Russian Embassy used Twitter to make its point with little panache.
“President Obama expels 35 Russian diplomats in Cold War deja vu. Everybody, including American people, will be glad to see the last of this hapless administration,” it read.
Mr Obama on Thursday sanctioned Russian intelligence services and their top officials, kicked out 35 Russian officials and closed down two Russian-owned compounds in the U.S. It was the strongest action the Obama administration has taken to date to retaliate for a cyberattack.
“All Americans should be alarmed by Russia’s actions,” he said. He added: “Such activities have consequences.”
