DOYLINE, La. (AP) — Authorities have begun moving 1 million pounds of improperly stored explosive powder to storage bunkers at the Camp Minden industrial site.

Webster Parish Sheriff Gary Sexton said work began at sunrise Saturday. Roads around Doyline were blocked off at 6 a.m.

Many of Doyline's 800 residents evacuated Friday. Some are staying at a Methodist camp in Minden and others at Lake Bistineau State Park, Sexton says.

Sexton says moving the powder could take through Monday, and schools in the town will be closed that day.

State investigators found the explosives while inspecting property leased by Explo Systems, where an above-ground storage magazine exploded in October.

Authorities say the powder isn't an imminent threat, but should be stored in a bunker approved by the Bureau of Alcohol, Tobacco, Firearms and Explosives.
