Four US Marines and a gunman are dead after twin attacks in military facilities in Chattanooga, Tennessee on 16 July. A Chattanooga police officer was also shot at US Naval Reserve Centre in the attacks, Mayor Andy Berke told reporters.

The gunmen has been identified by law enforcement as 24-year-old Muhammad Youssef Abdulazeez, a naturalized US citizen from Kuwait, according to The Hill. The Associated Press reported Abdulazeez lived in Hixson, Tennessee, just a few miles away from Chattanooga.

According to the Times Free Press, Abdulazeez's father, who works for City of Chattanooga Public Works Department, had been named a special, unarmed police officer in Chattanooga. The shooting began six miles west at a National Guard office on Lee Highway and later moved on to the Naval Reserve Centre, where the victims were shot, according to local media reports. USA Today reported that witnesses saw a gunman fire from a silver Mustang into the building.

A US military official told WRCB TV that the gunman fired 25 to 30 rounds at the military recruitment facility before driving to the reserve centre and opening fire there.

The Chattanooga police officer who was shot is said to be in a stable condition. Burke told reporters that he and Chattanooga Police Department Chief Fred Fletcher had visited the shooting scene and visited the officer at the hospital.
