An argument between two women led to a gunfight that left 11 people hurt in a busy tourist area of Savannah, Georgia, late Saturday, one of five weekend shootings in the city, two of which were fatal, authorities said.

Two people were injured in separate shootings Friday. Two more shootings Saturday resulted in two deaths. Then came the gunfire just before midnight Saturday near Savannah's Ellis Square.

The shooting broke out as two women argued in an area business, according to Police Chief Lenny Gunther, who didn't name the establishment.

"One shot rang out. That triggered other individuals to shoot," he said. "We had multiple individuals discharge their weapons to shoot at each other, which resulted in multiple people getting shot."

Ten of the 11 injured were hit by gunfire. Authorities did not say what caused the 11th injury. Victims were treated at the scene and "several" were taken to a hospital, police said. None of the injuries appeared life threatening.

Mayor Van Johnson said a proliferation of guns was a factor in the shootings and that reasonable gun control laws are needed. He also stressed the need for gun owners to keep their weapons from being stolen and for people carrying guns to know how and when to use them.

"We have to insist on smart gun laws," Johnson said at a Sunday news conference. "And then, on the other end, we have to insist that people act responsibly with those weapons."

The mass shooting happened a week ahead of the tourist-heavy Memorial Day weekend. Gunther sought to assure people that police staffing will be sufficient to keep the public safe.

Ellis Square is in Savannah's historic district, an area popular among tourists and locals. It was developed in 2010 and is known for a large fountain and a life-sized statue of songwriter Johnny Mercer.

The first two of Savannah's weekend shootings happened Friday. Each of those resulted in a non-life-threatening injury and an arrest. On Saturday, police answering a call about a home invasion found a dead juvenile at the home. Initial reports are that shots were fired after a resident confronted an armed intruder.

Still another shooting was reported at a Savannah intersection Saturday night that left one man dead and a juvenile injured.
