Prisoners holding about 600 hostages in a Guatemalan jail took their siege to a third day on Tuesday and considered a government offer of improved jail conditions and leniency in return for ending the uprising. About 1,000 soldiers, police and prison guards held machine-gun positions inside and outside the El Pavon prison's electrified fence awaiting the inmates' next move. "We've made a series of offers and we hope things will be resolved tomorrow (Tuesday)," Jose Manuel Campos, director of the Guatemalan prison system, told reporters late Monday outside the jail, 10 miles south of the capital. Inmates at the prison have held the hostages since a foiled breakout attempt Sunday. Four prison guards and four inmates were killed in a three-hour gunbattle Sunday that left about 50 injured.
