The governor of Texas, in the USA, has confirmed that 20 people have been killed in a shooting at a Walmart store in El Paso.
Police have confirmed that 26 people were injured in the shooting.
Law enforcement chief Greg Allen mentioned an alleged manifesto by the gunman, adding that the attack might have a “nexus” to hate crime.
He said, however, that the police are still looking into whether the document was indeed penned by the shooter.
They also confirmed that there was only one suspect taken into custody.
The man, believed to be the only gunman, surrendered to officers after they arrived at the scene, police said.
While the identities of the victims have not been revealed, Mexican authorities say three of the country’s nationals were killed in the shooting and a further six injured.
Mexican President Andres Manuel Lopez Obrador expressed condolences to the families via Twitter.
The attacker, who is now in custody, was armed with an AK-style rifle when he went on a shooting spree inside the Walmart on Saturday afternoon.
Harrowing videos have emerged on social media showing lifeless bodies lying outside and inside the store, as well as people taking cover inside the shop.
The suspect has been identified in the media as Patrick Crusius, a Texas native from Allen, near Dallas.
There have been reports of a Christchurch-massacre-inspired manifesto that the attacker allegedly left behind, espousing anti-Hispanic extreme-right views.
The shooting at the Cielos Vista Mall area started around 11.00 a.m. local time on Saturday, and the scene remained “active” for more than an hour.
Police said they received reports of multiple shooters, which later proved to be false.
Witnesses said a man armed with an AK-style rifle began shooting outside the Walmart and then went on a rampage inside the store.
Stills from CCTV videos appear to confirm the type of weapon used.
Footage from the scene shows heavily armed officers and police helicopters deployed.
