Putin purges more than 100 FSB agents in apparent retaliation amid Ukraine invasion quagmire

Russian President Vladimir Putin reportedly ousted about 150 agents from the FSB, the successor agency to the KGB. The ousted agents belonged to the Fifth Service, a division that Putin – then director of the FSB – set up in 1998 in order to carry out operations in the countries of the former Soviet Union, aiming to keep those countries in Russia's orbit.
