Ukraine's Attacks on Russia Escalate with Drones and Armed Resistance.

Dissident groups of Russian nationals opposed to President Putin and his war in Ukraine have carried out attacks in border cities including Bryansk and Belgorod. A collection of disparate anti-Kremlin armed groups are behind the attacks. They have divergent political views and ideologies, but they're united by a common goal: "To ensure the collapse of the Russian regime as quickly as possible," in the words of a masked gunman from one of the groups, who spoke with CBS News for a rare on-the-record interview.
