Ukraine’s top security official vows more “special operations” against Russia before year-end

Maliuk spoke in an interview with ICTV, Ukrinform reports.

"The Russians should expect more blasts... We never repeat ourselves and if they change their defense system against our naval drones, we, of course, are one step ahead. Everything needs to be done in the right time, you will see how it goes," he said.

According to Maliuk, since Russia unleashed the war, the security agencies have destroyed 809 Russian tanks, as well as other armored vehicles and e-warfare systems.

Among the successful operations performed by the SBU, Maliuk mentioned the strike hitting an A-50 early detection aircraft at the Machulishchi airfield in Belarus.

The head of the security agency informed that the teams operating attack drones are working in separate groups depending on the depth of planned strikes – from frontline areas to targets in

Russia’s rear (over 120km).

The SBU has already attacked 13 oil refineries across different regions of Russia in a bid to deplete Russia’s gasoline export profits feeding the war effort.
