Eight children, aged from one to 14 years old, have been killed in a shooting in Shreveport, Louisiana, which police are describing as a "domestic disturbance".

Officers said the incident began about 05:00 local time (10:00 GMT). A single gunman shot 10 people before fleeing in a stolen car. Police then chased and killed the suspected shooter.

"We have hurting families, we have hurting police officers, coroners' personnel," Shreveport Mayor Tom Arceneaux said. "This affects the entire community, so we all mourn with these families."

Police did not identify the suspected gunman or the victims, but said some of the children were related to the deceased man.

"This is a tragic situation – maybe the worst tragic situation we've ever had in Shreveport," the mayor added. He asked for prayers for the families and the city.

Police said there were mutiple crime scenes, including two homes on the same block on West 79th Street and a third residence in the neighbourhood on Harrison Street.

Shreveport Police Corporal Chris Bordelon said officers attended a home shortly before 06:00 local time and found the children.

"All of the deceased in this case are juveniles," Bordelon said.

He said officers determined the call was "domestic in nature" and added that one of those shot at the home had fled to a nearby residence.

After the shooting the suspected gunman carjacked a vehicle and started to flee, police said.

Bordelon said officers pursued him into another neighbourhood, and fired at the suspected gunman who is now deceased.

Police did not identify the shooter or the victims, saying they wanted to ensure family members are notified.

Shreveport Police Chief Wayne Smith said his heart went out to the entire community.

"I just cannot begin to imagine how such an event can occur," Smith said.

He added that the investigation is being conducted in coordination with the Louisiana State Police and with assistance from multiple other agencies.

"We are going to be working diligently however long it takes to get some answers to what has taken place," he said.

Louisiana Governor Jeff Landry said he and his wife are "heartbroken over this horrific situation, and we're praying for everyone affected".

"We're deeply grateful to the law enforcement officers and first responders working tirelessly on the scene," Landry added.

House Speaker Mike Johnson, who represents Louisiana's Fourth District, has also commented on the "heartbreaking tragedy".

"We're holding the victims, their families and loved ones, and our Shreveport community close in our thoughts and prayers during this incredibly difficult time," he said, adding that he was grateful for the quick response of local police.

The incident is the deadliest mass shooting in the US since January 2024, when eight victims were killed in Joliet, Illinois, according to the Gun Violence Archive (GVA), a nonprofit that tracks US gun violence.

GVA defines a mass shooting as an incident where four or more victims were shot, not including the suspect.
