Honduran jail riots kill 18

Police were called in to help restore order after prisoners attacked another group of inmates at the main jail in the capital, Tegucigalpa.

It is the second such clash in Honduras in recent days. Last week nine inmates died during rioting at a prison in the northern city of San Pedro Sula.

The violence is blamed on overcrowding and gang rivalry within prisons.

In the latest incident, 31 prisoners were attacked by cellmates with knives and guns hours after they were transferred from San Pedro Sula prison, officials say.
