ATTICA, N.Y. (AP) _ Authorities say they're investigating the deaths of two inmates at New York's maximum-security Attica Correctional Facility.

The state corrections department and state police say the inmates died on Thursday and a third inmate was hospitalized.

The deaths are being described as unattended. But officials aren't releasing any details Friday, citing the ongoing investigation.

The western New York prison was the site of the nation's deadliest prison riot in 1971.
