WASHINGTON (AFP) - US Senator Kay Bailey Hutchison said Thursday she was "shocked and saddened" by a shooting spree that killed seven and wounded 12 on a military base in her home state of Texas.

"Our dedicated military personnel have sacrificed so much in service to our country, and it sickens me that the men and women of Fort Hood have been subjected to this senseless, random violence," she said in a statement.

A spokesman for Fort Hood told AFP that gunmen killed seven people and wounded 12 others in the shooting.

"I am shocked and saddened by today?s outburst of violence at Fort Hood that has cost seven of our brave service members their lives and has gravely injured others. My heart goes out to their loved ones," said Hutchison.

"I know all Americans share this concern for the soldiers and their families who are affected by this tragedy," she said.
