At least 5 inmates were killed and 39 prisoners and guards were injured on Thursday in a brawl between gang members at a high-security prison in Honduras, judicial authorities said, writes Euronews.

The three-hour confrontation, involving live ammunition and at least one grenade, began when members of the Barrio 18 gang entered a section for members of the rival Mara Salvatrucha 13 gang in the La Tolva prison east of Tegucigalpa.

The facility houses more than 1,500 inmates, according to authorities. Thirteen of those injured are in a serious condition, prosecutor Sara Gómez told a local television newscast.
