This is a significant development. Russia has vowed a response to the targeting of its territory and civilians.

“Moscow is considering ‘surgical retaliatory strikes’ on the Ukrainian territory after the standoff has led to first civilian victims among Russians on Russia’s territory, a Kremlin source told Kommersant Monday,” RIA Novosti reports today.

The Russian Foreign Ministry announced Sunday it has protested the shelling and called it a provocation that might have irreversible consequences. Deputy Russian Foreign Minister Grigory Karasin said earlier that Russia promises “harsh demarches” against Ukrainian authorities over the incident.

Russian officials summoned the Ukrainian charge d’affaires to the Foreign Ministry in Moscow to protest the attack, according to the Associated Press.

The Russian Foreign Ministry said the incident was an “aggressive action” that “highlights the extremely dangerous escalation of tensions on the Russian-Ukrainian border and may have irreversible consequences, the responsibility for which lies on the Ukrainian side.”
