1 killed, 2 injured: Russia vows response to Ukraine shelling Russian city

An artillery shell from Ukraine has hit a private house in the Rostov region of Russia, killing a citizen and leaving two more injured. The Russian Foreign Ministry promises heavy consequences.
Reportedly up to six mortar shells exploded on Sunday in the small Russian town of Donetsk, which has the same name as the Ukrainian city and is situated right on the Ukrainian border.
Ukraine’s charge d'affaires in Russia has been summoned to the Foreign Ministry where he was handed a note of protest in the strongest terms.
