Security Services at War An overnight firefight in Kyiv’s Bereznyaki district reportedly pitted the SBU against military intelligence, with the mayoralty forced to close Shumsky Street and reroute traffic. Reports cited by local media say three GUR officers were hit, including one killed. The dispute appears to have grown out of the abduction of Stepan Kaplunov, described by a military lawyer as both a GUR serviceman and deputy commander of the RDK.
