Paris – The United States and its European allies on Monday expelled scores of Russian diplomats in a coordinated action against Moscow which they accuse of poisoning an ex-spy in Britain.
The United States expelled 60 alleged "spies" posted around the country and at the Russian mission to the United Nations.
It also closed the Russian consulate in Seattle over alleged spying at the nearby Kitsap submarine base and Boeing.
The retaliation against Moscow was taken "in response to Russia's use of a military-grade chemical weapon on the soil of the United Kingdom", White House press secretary Sarah Sanders said.
Canada ousted four diplomats, calling the nerve agent attack "a despicable, heinous and reckless act".
Australia followed suit with Australian Prime Minister Malcolm Turnbull saying two Russian diplomats had seven days to leave.
Sixteen EU states have joined Britain in expelling Russian diplomats following a European Council decision last week to react to Moscow within a common framework.
"Additional measures including further expulsions are not to be excluded in the coming days and weeks," EU President Donald Tusk said.
Britain itself has already kicked out 23 Russian diplomats, with Moscow retaliating with a tit-for-tat move.
President of the Ukraine, Petro Poroshenko called for even more action to be taken.
"The next step is to increase the price that Moscow has to pay for its international crimes, including the strengthening of personal, financial and economic sanctions," he said.
