One of the shooters has been apprehended, Fort Hood spokesman Sgt. Maj. Jamie Posten told CNN.

“At this point we’re looking for the other shooter,” Posten said. Asked for a description, he said, “we’re trying to develop that information.”

The shooters were wearing military uniforms, but it was unclear whether they were soldiers, said U.S. Sen. Kay Bailey Hutchison, R-Texas.
