At least three inmates were wounded, one of them seriously, in a shooting Tuesday at the Honduran national penitentiary in Valle de Tamara, warden Ismael Colindres said.

The shooting happened in the maximum-security section of the prison, located 25 kilometers (15 miles) north of Tegucigalpa, where an armed inmate "fired at other inmates, wounding three," Colindres said.

The reason for the shooting has not been determined, the warden said.

Two of the wounded inmates were transported to the Teaching Hospital in Tegucigalpa, Colindres said, adding that the shooter had been identified.

The third wounded inmate was treated at the prison's clinic.

The wounded inmates were identified as Arnold Hernandez, Melvin Cruz and Norlin Varela, the warden said, without specifying which of the three was the one in serious condition.

The Honduran prison system operates 24 facilities, with most of them overcrowded and unsafe.

Shootings, riots and seizures of arms and drugs are common in the Central American country's prisons.

A fire killed 360 inmates and a female visitor on Feb. 14 at the Comayagua prison farm, located about 80 kilometers (49 miles) north of Tegucigalpa. EFE
