US ambassador to Moscow, Jon Huntsman, has been summoned to the Foreign Ministry and told the news by deputy FM Sergey Ryabkov, Lavrov said at the press conference following a meeting with the special UN envoy for Syria Staffan De Mistura.
On Monday, Washington expelled 48 Russian diplomats from the bilateral mission and 12 more from the UN mission, and shut down the Russian consulate in Seattle. Canada, Australia and a number of US allies in Europe have followed up by expelling over 90 Russian diplomats.
In addition to the mirror response to the US, Moscow will expel the equal number of diplomats from those countries, Lavrov said.
The expulsions began on March 14, when the UK declared 23 Russian diplomats personae non grata, claiming that Moscow was “highly likely” behind the alleged poisoning of former spy Sergey Skripal and his daughter Yulia with the chemical agent “novichok.” Russia has denied the allegations and requested the British government to provide evidence. So far, there has been none.
