Chechen leader vows revenge after drone attack

Chechen leader Ramzan Kadyrov promised on Tuesday to take revenge for a drone attack that caused a fire at a military training academy in his south Russian region. Ukraine has frequently struck Russia with drones in the course of the war, but Tuesday's attack appeared to be the first against Chechnya. "They've bitten us - we will destroy them," Kadyrov told reporters in a video published by Russian state news agency RIA.
