Four Marines were killed today when a gunman opened fire at two separate military centers in Chattanooga, Tennessee.

The suspect, who was also killed, has been identified as Muhammad Youssef Abdulazeez, Fox News chief intelligence correspondent Catherine Herridge reported.

According to AP, he is from Kuwait and lived in Hixson, Tennessee, which is just a few miles across the river from Chattanooga.

Law enforcement officers have swarmed the house believed to belong to the gunman. An Associated Press reporter saw officers with weapons drawn at the house and two females were led away in handcuffs.

It's not clear who these females are.

The gunman attacked a recruiting center before driving to the Navy Operational Support Center and Marine Corps Reserve Center and killing four Marines before he was shot, authorities said.

Sources told Fox News that police chased the gunman to the second facility, where the killings took place. A police officer was wounded at the first location, but his injuries are not life threatening.

Officials said earlier at a news conference that the attack was being investigated as domestic terrorism.

Herridge said known ISIS-affiliated Twitter accounts were celebrating the attack, which comes at the end of Ramadan.
