Shreveport, La. ? More than 10 explosions rocked a bomb recycling plant Thursday in northwestern Louisiana, forcing the evacuation of an entire town and more than 400 prisoners from a nearby jail, authorities said.

No injuries or deaths were reported.

A fire at the Explo Systems Inc. site at the Louisiana Army National Guard’s Camp Minden triggered a major explosion involving two military bombs about 8:30 a.m., state police said. In the ensuing hours, more than 10 explosions – some intense, some minor – went off inside the plant as the fire continued to burn and thick smoke billowed from the plant, authorities said.

Authorities evacuated Doyline, a town of 800 people about 20 miles east of Shreveport, closed two schools and emptied the Webster Parish jail, said Bobby Igo, chief deputy for the Webster Parish sheriff.

By late afternoon, the main fire had burned itself out, but authorities were monitoring small hot spots as a hazardous materials survey team examined the damage.
