Gunman kills 20 in rampage at Walmart store in Texas

El Paso, Aug 4: A gunman armed with a rifle killed 20 people at a Walmart in El Paso, Texas, on August 3 and wounded more than two dozen before being arrested, authorities said, after the latest U.S. mass shooting sent panicked shoppers fleeing.

Many of those in the busy store were buying back-to-school supplies when they were caught up in the rampage, which came just six days after a teenage gunman killed three people at a food festival in Northern California.

Announcing the death toll at a news conference, Texas Governor Greg Abbott said it was “one of the deadliest days in Texas history.”

Mexico's President Manuel Lopez Obrador said three Mexicans were among the dead and six were among the wounded. It was the eighth worst mass shooting in modern U.S. history, after the 1984 shooting in San Ysidro that killed 21 people.

The suspect was identified as a 21-year-old white male from Allen, Texas, a Dallas-area city some 650 miles (1,046 km) east of El Paso.

Asked during a CNN interview about reports of disturbing social media posts apparently made by the suspect, Texas Attorney General Ken Paxton said he would not be surprised in any way.

still interviewing him.”

El Paso police chief Greg Allen said authorities had a manifesto from the suspect that indicates “there is a potential nexus to a hate crime.”

The suspect was taken into custody without incident, according to authorities.

Citing a law enforcement source, El Paso television station KTSM published on its website what it said were two photos of the suspect taken by security cameras as he entered the Walmart.

The images showed a young white man wearing glasses, khaki trousers and a dark T-shirt, and pointing an assault-style rifle. He appears to be wearing headphones or ear defenders.

Reuters could not immediately verify the authenticity of the images.

'Very bad, many killed'

U.S. President Donald Trump said on Twitter that the reports from El Paso were “very bad, many killed.”

University Medical Centre of El Paso received 13 patients, including one who died, hospital spokesman Ryan Mielke told CNN.

Some of the patients were in surgery while others were in stable condition, he added.

Two of the patients who arrived at the hospital were children with non-life threatening injuries who were transferred to El Paso Children's Hospital, he said.

Local media said there was such an overwhelming response to an appeal by the police department for blood donations to help the wounded that long lines formed at medical centres, some of which had to tell would-be donors to come back on Sunday.

'People were panicking'

Multiple law enforcement agencies raced to the scene at the Walmart and nearby Cielo Vista Mall, including police, state troopers, Homeland Security agents and border patrol.

Shoppers fled for their lives, including Kianna Long who was at the Walmart with her husband when they heard gunfire.

“People were panicking and running, saying that there was a shooter,” Ms. Long said. “They were running close to the floor, people were dropping on the floor.”

Ms. Long and her husband sprinted through a stock room at the back of the store before sheltering with other customers in a steel container in a shipping area.

Graphic video from the scene posted on social media showed what appeared to be dead bodies and wounded victims. Tales of heroism also emerged.

Walmart said in a statement, “We're in shock over the tragic events at Cielo Vista Mall... We're praying for the victims, the community & our associates, as well as the first responders.”

Stores at the mall were also locked down as police officers cleared the shopping centre in the east of the city, which lies on the southern U.S. border with Mexico.

Video posted on Twitter showed customers at one department store being evacuated with their hands up.

Mass shootings are common in the United States. On Sunday, a teenage gunman opened fire with an assault-style rifle on the crowd at a food festival in Northern California, killing three people before fatally shooting himself.

At a Democratic presidential candidate forum in Las Vegas a clearly emotional Beto O'Rourke, a former Texas congressman who is from El Paso, broke the news to the audience that he had just heard about the deadly mass shooting in his home city.

Mr. O'Rourke said he had spoken to his wife Amy, who was driving in the city with one of their children. Addressing reporters, he teared up and struggled to deliver a short statement.

“I am incredibly saddened and it's very hard to think about this,” he said. “El Paso is the strongest place in the world. This community is going to come together. I'm going back there right now to be with my family, to be with my home town.”
