At least six dead in prison riot

At least six people died in an overcrowded Guatemala prison on Sunday as prisoners, some armed with AK-47 assault rifles, rioted.

Special police forces and the army were sent to take control of the prison, a spokesman for Guatemala's prisons said.

Guatemala awarded Mexican construction company ICA, which has been struggling under a heavy debt burden, a multi-million dollar contract to expand the prison late last year, according to official contract data.
