The incident—just the latest evidence of Vladimir Putin’s flailing war beginning to blow up within Russian borders—occurred in Novoshakhtinsk, just 12 miles or so from the border with Ukraine.Law enforcement sources cited by Russia’s TASS news agency and Komsomolskaya Pravda identified the gunman as a deserter, without giving further details.Mash reported that he came from the direction of the border with Ukraine before opening fire on police officers using a machine gun.The Russian Telegram channel Baza reported that police first noticed the man while they were conducting an investigation into a missing person nearby.Just over the border in Ukraine, hundreds of Russian soldiers who refused to fight have forcibly been held in basements and cold garages in recent months, according to human rights groups and family members who’ve spoken to independent Russian outlets."
