A gunman has been shot dead by police after firing shots at a federal courthouse in West Virginia.
The US Marshals Services said officers fired at the man after he shot up to two dozen rounds at the courthouse in Wheeling.
The man was said to have fired 15 to 25 shots at the court building with what officials described as an assault-style rifle.
Marshals Service chief deputy Mike Claxton said one person inside the courthouse suffered minor injuries from flying debris.
Mr Claxton said investigators were seeking a search warrant for the gunman's home in the hope of determining the motive and if he acted alone.
Asked if the gunman had any issue with the US government, Mr Claxton said: "We're really digging hard at this point to find out."
He said the man started firing from a car park across from the federal building. "He was observed in the parking lot very quickly after the first shots were fired," he said.
Courthouse security and local police ultimately returned fire and hit the man.
The building houses a variety of courtrooms and related offices, including judges, prosecutors and law enforcement.
