Citing law enforcement sources, CBS News reported Thursday that Muhammad Youssef Abdulazeez is the name of the suspected gunman who shot at two military-related facilities in Chattanooga, Tennessee.

Five people were killed on Thursday including a suspected gunman who opened fire at two military-related facilities in Chattanooga, Tennessee in an attack local officials described as an act of domestic terrorism.

The other four killed were Marines at a Naval Reserve Center, a military official said in Washington, DC. The suspected shooter, who has not been identified, is believed to have lived in the area, local police said.

“We are treating this as an act of domestic terrorism,” said Bill Killian, the U.S. Attorney for the Eastern District of Tennessee, adding that no official determination of the nature of the crime had yet been made.

Three others were wounded in the attacks that began at about 10:45 a.m. local time and ended about 30 minutes later.

Chattanooga Police Chief Fred Fletcher said at a joint news conference the gunman acted “brutally and brazenly.”

Witnesses and local media reports said the gunman, driving an open-top Ford Mustang, fired at two locations including a military recruiting center and a U.S. Navy Reserve center about six miles (10 km) apart. Witnesses said they heard scores of shots.

A White House spokesman said President Barack Obama had been told about the shooting.

“The President has been briefed by his national security staff on the Chattanooga shooting, and will continue to get updates as warranted,” said spokesman Eric Schultz.
