Sirhan Sirhan, imprisoned for more than 50 years for the 1968 assassination of Sen. Robert F. Kennedy, was hospitalized Friday after being stabbed by a fellow inmate at a San Diego prison.

The stabbing occurred Friday afternoon at the Richard J. Donovan Correctional Facility near San Diego, according to a statement from the state Department of Corrections and Rehabilitation.

'Officers responded quickly, and found an inmate with stab wound injuries. He was transported to an outside hospital for medical care, and is currently in stable condition,' the statement said.

The statement did not name Sirhan, but a government source with direct knowledge confirmed that he was the victim. The source spoke under condition of anonymity, citing prison privacy regulations.
