US Defense Secretary, Chuck Hagel, has called the shooting at Fort Hood in Texas a "terrible tragedy". Fort Hood was the scene of a mass shooting in 2009. Hagel was speaking at a news conference in Honolulu, where he was meeting Asian defense ministers.
"We know there are casualties, both people killed and injured, any time you lose to a few of people, when this kind of tragedy, the solutions is a problem, no matter what questions we are challenging, we will do it," he said.
