The Kremlin said the Russian military will do everything to minimize and eliminate the threat of shelling of Russian cities by Ukraine's armed forces, following repeated shelling of the border city of Belgorod.
"Our military will continue to do everything to first minimize this danger, and then completely get rid of it," the Kremlin's Press Secretary Dmitry Peskov told reporters, news agency Tass reported.
Ukraine again shelled the Russian border city of Belgorod Monday evening, leaving three people injured, Russian officials said.
Separately, Russia's defense minister claimed Moscow retained the "strategic initative" in the war while a Ukrainian official warned earlier of a deficit of anti-aircraft guided missiles.
