A shocking shooting in Kyiv has left at least six people dead after a gunman opened fire on civilians before taking hostages inside a supermarket. The attacker was later killed by police following a tense standoff. What’s raising serious concern is the suspect’s background — investigators are now probing possible connections to Russia, including past travel, financial links, and extremist online activity. Authorities are examining whether the attack could be part of a broader pattern of hybrid warfare tactics aimed at spreading fear and instability.
