Zelenskyy fires head of Ukraine Security Service, announces hundreds of criminal treason cases

Ukrainian President Volodymyr Zelenskyy said his country is undergoing a "self-purification" process as he looks to root out officials and law enforcement officers who are guilty of corruption and treason.

"As of today, 651 criminal proceedings have been registered regarding treason and collaboration activities of employees of prosecutor's offices, pretrial investigation bodies, and other law enforcement agencies," the Ukrainian president said. "In 198 criminal proceedings, relevant persons were notified of suspicion. In particular, more than 60 employees of the prosecutor's office and the Security Service of Ukraine remained in the occupied territory and are working against our state."
