Two inmates were killed and others were injured in a Nebraska prison Thursday after inmates revolted against staff members and started a fire in a courtyard.
Prison officials said the disturbance at the Tecumseh State Correctional Institution involved about 40 inmates in a unit with 128 prisoners.
The prison was placed on lockdown for several hours after the inmates refused to return to their cells.
More details on the disturbance
No prison employees were injured. An unspecified number of inmates suffered injuries that weren't life-threatening, said Department of Correctional Services Director Scott Frakes.
He told the Associated Press that the two unidentified inmates killed were found inside the housing unit. "This incident is a reminder that this is a dangerous business," Frakes said.
