CHICAGO: A gunman killed four children and two adults during a domestic dispute in Texas on Wednesday before being taken into custody, officials said.
The shooting happened in Spring, outside Houston, Harris County Constable Ron Hickman told AFP.
One of the killed children died after arriving at hospital. The two slain adults were men, Hickman said.
Before being taken to hospital, a wounded woman was able to tell authorities where the suspect, a relative, was headed, triggering a police chase that lasted at least 20 minutes.
"We got him in a cul-de-sac," said Hickman, after at least an hour had passed during which the suspect sat in his vehicle surrounded by about 50 police with their guns drawn. There were at least a dozen patrol cars waiting to pounce.
The Harris County Sheriff's Office later said on Twitter that the suspect was in custody. No one was immediately available at the press office.
A hostage team had been negotiating with the suspect for him to surrender. The suspect had not taken anyone hostage.
Hickman said a large military-style SWAT truck parked right in front of the suspect's vehicle to prevent him from fleeing.
Some residents took to Twitter to thank the authorities.
"@SheriffGarcia Great job by your team this evening in our Spring community, thank you," Susan Wheeler wrote on Sheriff Adrian Garcia's Twitter page.
The shooting was the latest in a spate of similar incidents in a country plagued by gun violence.
President Barack Obama has warned that America needs to do some "soul-searching" on gun control, which remains relatively lax despite regular gun rampages.
On May 23, a student with mental problems killed six people and then himself in California, while on June 5 a gunman killed one person and injured two others on a campus in Seattle.
In June, a couple with possible anti-government militia links shot dead two police and a civilian in Las Vegas, and a teenage gunman shot a 14-year-old student dead at an Oregon high school. (AFP)
