Ukrainian President Volodymyr Zelensky abruptly dismissed two of the country’s top law enforcement officials earlier this week, accusing both of treason.

During his daily video address, the Ukrainian President said both officials lead spy-riddled agencies. While he did not personally identify them, Zelensky disclosed that further investigation found several more employees within the officials’ departments who were allegedly colluding with Russia.

“Such an array of crimes against the foundations of the national security of the state … pose very serious questions to the relevant leaders,” the president said. “Each of these questions will receive a proper answer.”

Later that day, the president’s office confirmed that these two officials were prosecutor general Iryna Venediktova and state secret service (SBU) director Ivan Bakanov, a childhood friend and former close adviser of Zelensky.
