Authorities say multiple people were shot and killed and a suspect was taken into custody in an attack at a shopping complex in El Paso, Texas.

Police Sgt. Enrique Carrillo told reporters Saturday that the attack at or near the Cielo Vista Mall had ended. He didn't say how many people were wounded or killed, but NBC News reports that a University Medical Center of El Paso official said it had received at least 10 seriously injured victims and that some victims were taken to other hospitals.

The White House says President Donald Trump has been briefed on the shooting and has spoken to Attorney General William Barr and Gov. Greg Abbott.

El Paso, which has about 680,000 residents, is in West Texas sits across the border from Juarez, Mexico.

Presidential candidate and former Texas congressman Beto O'Rourke appeared a bit shaken as he appeared at a candidate forum in Las Vegas on Saturday shortly after news of the shooting in his hometown was reported.

O'Rourke said he had called his wife before taking the stage and said the shooting shatters "any illusion that we have that progress is inevitable" on tackling gun violence.

The Democrat said he'd heard early reports that the shooter might have had a military-style weapon, saying we need to "keep that (expletive) on the battlefield and do not bring it into our communities."

"We have to find some reason for optimism and hope or else we consign ourselves to a future where nearly 40,000 people are year will lose their lives to gun violence and I cannot accept that," O'Rourke said.
