Twenty-four countries -- including 17 member-states of the European Union -- have expelled more than 100 Russian diplomats over the attempted murder in England of Russian national Sergei Skripal and his daughter.
Izvestia pro-Kremlin daily denounced what it called a "flash mob", while Nezavisimaya Gazeta daily stressed that "never before have there been such coordinated expulsions".
"Relationships between Russia and the West are entering a period of an all-out Cold War," political analyst Fedor Lukyanov wrote in Vedomosti business daily.
"This is not an end of escalation. It will most probably worsen."
Kommersant business daily wrote that these "measures of unprecedented severity... are yet another round of aggravation of tensions in Russian-Western relations".
Political analyst Stanislav Belkovsky said Russia's foreign policy has been fired by "the concentrated energy of self-destruction" since 2014, the year when Moscow annexed Ukraine's Crimean peninsula, incurring retaliatory economic sanctions from the West.
Skripal is a former Russian military intelligence officer who sold secrets to Britain and moved there in a 2010 spy swap.
He and his daughter Yulia remain in critical conditions after they were found unconscious on a park bench in the English city of Salisbury on March 4.
Britain says a military-grade nerve agent was used to poison them, pointing a finger at the Kremlin, which has angrily rejected accusations of being behind the crime.
