NEW ORLEANS — Gunmen opened fire on dozens of people marching in a neighborhood Mother's Day parade in New Orleans on Sunday, wounding at least 19 people, police said.
The FBI said the shooting appeared to be "street violence" and wasn't linked to terrorism.
Many of the victims were grazed and most of the wounds weren't life-threatening, according to authorities, though at least three people had serious wounds. No deaths were reported.
The victims included 10 men, seven women, a boy and a girl. The children, both 10, were grazed and in good condition.
Mayor Mitch Landrieu urged witnesses to come forward with information during a news conference Sunday night at a hospital where victims were taken.
"These kinds of incidents will not go unanswered. Somebody knows something. The way to stop this violence is for you all to help," he said.
Mary Beth Romig, a spokeswoman for the FBI in New Orleans, said federal investigators have no indication that the shooting was an act of terrorism.
As many as 400 people joined in the second-line procession that stretched for about three blocks, though only half that many were in the immediate vicinity of the shooting, said police Superintendent Ronal Serpas. Officers were interspersed with the marchers, which is routine for such events.
Police saw three suspects running from the scene in the city's 7th Ward neighborhood. No arrests had been made as of early evening.
Second-line parades are loose processions in which people dance down the street, often following behind a brass band.
The shootings took place about 1.5 miles from the heart of the French Quarter and near the Treme neighborhood, which has been the centerpiece for the HBO TV series Treme.
