From the article:
A brutal prison female gang war left 46 women dead after rivals set fire to their cells, reports say.
The gang members, armed with guns and machetes, locked the women in their cells.
A police spokesperson said some bodies were burned so badly it was "difficult to identify them."
The attack is thought to have been carried out by members of the notorious Barrio 18 gang against the rival Mara Salvatrucha, also known as MS-13.
