An Uzbek man who was serving 25 years in prison for terrorism charges was sentenced to an additional 20 years for attempting to kill a prison warden, according to a Department of Justice press release. U.S. District Judge Virginia A. Phillips gave 36-year-old Fazliddin Kurbanov the maximum sentence for attempted murder after he tried to slit the throat of a prison warden at Federal Correctional Institute in Victorville, California, with a prison-made knife in 2016. Kurbanov told the court Monday that he was “not sorry” about the incident and that the warden was “supposed to die.” He also expressed “extreme animosity toward the United States” during his sentencing hearing. Kurbanov pleaded guilty in March, and he will serve his additional 20 years consecutively with the 25 years he is serving for providing support to the Islamic Movement of Uzbekistan. The warden suffered serious injuries but has since recovered from the attack.
