The EU has recalled its ambassador from Moscow for consultations over an incident it called "a grave challenge to our shared security." Britain and Russia have expelled 23 of each other's diplomats since the attack, which has sparked an east-west diplomatic crisis reminiscent of the Cold War. Czech Prime Minister Andrej Babis said it was "probable" his country would also kick out Russian diplomats, noting that discussions were still ongoing. Irish Prime Minister Leo Varadkar said Ireland would conduct a security assessment of Russian diplomats with a view to possibly expelling those who are not legitimate. Danish Prime Minister Lars Lokke Rasmussen said his country would also consider "whether we should take unilateral steps."
