DOYLINE, La. (AP) — Authorities are slowly moving some of the 6 million pounds of explosives improperly stored at a munitions recycling facility because they feared a chain reaction blast could have spread through corridors packed with explosive materials, the sheriff of the threatened area said Tuesday.

A voluntary evacuation order for Doyline, a town of 800 people near the site and about 25 miles east of Shreveport, was expected to remain in effect until at least Friday while the material was moved to a safer location elsewhere on the sprawling Camp Minden grounds.
