(Reuters) - At least four people were injured in an explosion at a U.S. Army facility in rural Franklin County, Pennsylvania early on Thursday, local emergency officials said.
Three of the people were airlifted to burn units at local hospitals after the blast at Letterkenny Army Depot, which is about 50 miles southwest of Harrisburg, Colonel Steven Ledbetter told a news briefing.
The explosion and subsequent fire occurred in a paint production facility and was quickly brought under control by Franklin County firefighters, Ledbetter said.
“We’re investigating the cause of the incident,” he added. The 18,000 acre Letterkenny facility employs about 3,600 people who provide support for U.S. missile systems, according to its website.
