PHOENIX -- Four people were killed and 14 others were reportedly wounded in a shooting Wednesday at Fort Hood, Texas.
A Justice Department internal report said the gunman was killed by an apparent self-inflicted wound. That person was counted among the dead.
The committee chairman, Rep. Michael McCaul, R-Texas, told CNN he had been briefed on the deadly incident and said there were also 14 injuries. Authorities were concerned another shooter might be at large, but no link to terrorism has been discovered, the lawmaker said.
According to KCEN-TV, four soldiers wounded in the shooting were in critical condition.
The base released a statement that confirmed the situation, but not much else.
There has been a shooting at Fort Hood and injuries are reported. Emergency crews are on the scene. No further details are known at this time.
On Tuesday, Fox News reported the Federal Bureau of Investigation was searching for an Army recruit who may have been planning a "jihad against U.S. soldiers."
The alert, whose legitimacy was confirmed by military and law enforcement officials, stated that a man identified as Booker had told friends of his "intention to commit jihad." Booker, who is also known as Muhammad Abdullah Hassan, was recruited by the U.S. Army in Kansas City, Mo., in February 2014 and was scheduled to report for basic training on April 7. But he was discharged last week, apparently after law enforcement authorities learned of his alleged plan.
Fort Hood was put on lockdown and employees were told to shelter in place. A witness said as many as 21 ambulances were on the scene.
The base was the scene of a mass shooting in 2009. Thirteen people were killed and more than 30 wounded in what was the deadliest attack on a domestic military installation in history.
White House spokesman Josh Earnest said the president has been informed of the reports of a shooting at Fort Hood and will continue to receive updates as he attends a pair of Democratic Party fundraisers in Chicago.
