Sirhan Sirhan, the man convicted of assassinating Robert F Kennedy, has been stabbed at a California prison.
Authorities said a stabbing happened at a prison near San Diego and Sirhan is now in a stable condition in hospital.
Sirhan, 75, is serving a life sentence at the Richard J Donovan Correctional Facility, where the stabbing took place.
The suspected attacker, a fellow inmate, has been placed in isolation.
Sirhan was convicted of murdering presidential hopeful Kennedy, who he shot three times at the Ambassador Hotel in Los Angeles on June 5, 1968.
Kennedy was shot in the kitchen of the hotel, shortly after declaring victory in California’s Democratic presidential primary to cheering crowds.
At his trial in 1969, Sirhan was originally sentenced to death. Three years later, however, his sentence was commuted to life in prison when California briefly outlawed capital punishment.
