Workers have found two mortar shells in rural Etowah County at a site that was a chemical weapons training camp during World War II. The Army Corps of Engineers says contractors unearthed the munitions in an area that was part of Camp Sibert during the 1940s. Workers have been scouring the land for unexploded munitions for years as part of a federal cleanup program. The Gadsden Times quoted Etowah County emergency managers as saying the shells don’t present a danger to the public. Workers plan to detonate the mortars, which contain an unknown liquid.
