TEHRAN, Young Journalists Club (YJC) - Police in the Tennessee city of Nashville said the suspect in the country's latest mass shooting may have had "mental issues," and the incident led the city's mayor to issue an unusually blunt call for "comprehensive gun reform."
The Metro Nashville Police Department said 3 people were killed at place and one died in hospital because of severe injuries.
Meanwhile 2 other people were wounded and taken to the Vanderbilt University Medical Center in Nashville.
Police identified the suspect as 29-year-old Travis Reinking and said he could be armed with a rifle and a handgun, after firing an AR-15 semi-automatic rifle at the restaurant, where he was nude except for a green jacket.
A military-style weapon, the AR-15 has been regularly used in US mass shootings.
AR-15 rifles were used to kill 58 people in Las Vegas last October, while Florida school shooter Nikolas Cruz in February opened fire on his former high school with an AR-15 style rifle, killing 17 students and staff members.
