Five inmates at Folsom prison in California have been shot by guards during a riot.
None of the prisoners' injuries is believed to be life threatening and no guards were injured.
The riot involved about 200 inmates.
Three of the wounded inmates were reportedly taken to local hospitals, while two others were treated at the medium-security prison.
The prison, which holds about 4,000 prisoners, has now been brought under control and the cause of the riot is being investigated, the authorities said.
Folsom State Prison, about 32km from the state capital Sacramento, was made famous by the US singer-songwriter Johnny Cash in his 1955 song Folsom Prison Blues.
Cash also performed a concert for inmates in the prison's refectory in 1968, which became a famous album.
