President Obama, speaking from the Oval Office, described Thursday's deadly shooting of four Marines as a "heartbreaking circumstance," and said the FBI would take the lead in the investigation. "I want everybody to understand we will be thorough and prompt on figuring out exactly what happened," the president said.
The suspected gunman, Mohammod Youssuf Abdulazeez, 24, is dead, after an attack on two military facilities in Chattanooga, Tennessee. The gunman, "armed with numerous weapons," began the spree at a recruiting center, and then moved on to a nearby reserve center.
At least three other people were injured, including a police officer and a Marine recruiter.
