The suspect in the shootings that left five people dead on Thursday in Chattanooga, Tennessee, has been identified as Muhammad Youssef Abdulazeez, the FBI has confirmed.
The shootings took place at two military facilities. Four Marines and the gunman were killed. Three other people were injured, including a police officer who was shot in the ankle, Chattanooga Mayor Andy Berke said during a press conference.
The shooter used several guns in the attack that started at a military recruitment center around 10:45 a.m., authorities said. He then drove to a military reserve center about 7 miles away, where he opened fire.
On Thursday afternoon, authorities swarmed the house where they believe Abdulazeez lived, according to the AP.
The incident is being investigated as an act of domestic terrorism, U.S. Attorney Bill Killian said at the news conference.
"As a city, we will respond to this with every available resource we have," Berke said.
