Police in New Orleans have vowed to track down the gunmen who wounded 19 people at a Mother's Day parade, the latest violence to hit a celebration in the city this year.
The FBI called the attack "street violence" and said federal investigators have no indication the shooting was an act of terrorism. New Orleans has one of the highest violent crime rates among US cities.
The victims were 10 men, seven women, a boy and a girl, and at least three of them were seriously wounded. Of the rest, many were grazed by the shots including the children, both 10 years old.
Detectives are collecting any surveillance video they can find and gathering evidence from where gunmen opened fire on Sunday on the parade of hundreds of revellers. Mobile phone videos after the shooting showed victims lying on the ground, blood on the pavement and others bending down to comfort them.
It is not the first time gunfire has shattered a festive mood in New Orleans this year. Five people were wounded in January after a Martin Luther King Jr Day parade, and four were wounded in a shooting in the French Quarter before Mardi Gras, a popular tourist destination.
"The specialness of the day doesn't appear to interrupt the relentless drumbeat of violence," Mayor Mitch Landrieu said outside a hospital where victims were being treated.
As many as 400 people came out for the second-line Mother's Day procession – a boisterous New Orleans tradition. Police saw three suspects running from the scene. No arrests had been made yet.
