Tragedy strikes again at Fort Hood

An Iraq War veteran being treated for mental illness opened fire Wednesday on fellow service members at the Fort Hood military base, killing three people and wounding at least 16 before committing suicide at the same post where more than a dozen people were slain in a 2009 attack, authorities said.

The shooter apparently walked into a building and began firing a .45-caliber semi-automatic pistol. He then got into a vehicle and continued firing before entering another building. (AP)
