At least 36 people were killed in weekend clashes in Honduran prisons as the military and police try to regain control after a spate of murders linked to the criminal gangs plaguing the country.

On Sunday afternoon, 18 gang members died in a clash between inmates at El Porvenir prison, 60 kilometers (40 miles) north of the capital Tegucigalpa.

"Firearms, knives and machetes" were used in the brawl, which also left 10 wounded, Lieutenant Jose Coello, a spokesman for the National Inter-Institutional Security Force (Fusina), told local media.

On Friday night, 18 prisoners died and 16 were wounded in a shooting at the prison in the port town of Tela, northwest of the capital.

The killings came shortly after President Juan Orlando Hernandez - grappling with a wave of prison killings - ordered the army and the police on Tuesday to take control of the country's 27 prisons, which are badly overcrowded with some 21,000 inmates.

The security forces later said they were deploying about 1,200 military and police in 18 facilities classified as "high risk."

Hernandez announced the crackdown after the killings on December 14 of five members of the feared MS-13 gang by a fellow detainee at the high-security prison in La Tolva, east of Tegucigalpa.

That came just a day after Pedro Idelfonso Armas, the warden of Honduras's main high security prison in Santa Barbara, El Pozo, was shot dead in the south of the country.

The security ministry had suspended Armas shortly before his death, amid an investigation into his presence during the October 26 murder of Magdaleno Meza, a drug kingpin whose confession and notebooks linked him to the president's brother, Juan Antonio "Tony" Hernandez.
