Kgb and Chechnya?

I have read somewhere that Russsia's FSB the former KGB has killed over 119 leaders of Chechen terrorist organizations?

Is that true and aren't they supposed to be a Domestic Russian Law-Enforcement agency?

Wouldn't that be like the U.S. FBI being sent to Iraq or Afganistain to kill Al-Qeada?
