EL PASO, TEXAS -- Police in El Paso, Texas, responded Saturday to an active shooter in the area of the Cielo Vista Mall, the agency tweeted.
The mayor of El Paso, Dee Margo, reportedly said there were multiple fatalities from the shooting.
Word of multiple shooters has been ruled out. One person is in custody and buildings are still being cleared out.
A hospital in El Paso took in at least 10 victims with level 1 injuries, which is the most serious level, and said that several hospitals have taken in several victims.
At least three businesses in the area were on lockdown.
Three Walmart employees took refuge at a Landry's Seafood House, restaurant manager Oscar Collazo told CNN. The women appeared "shook up" but not injured.
Landry's had already gone on lockdown, he said but opened its doors when the employees ran there.
"We never thought it would be so close to us this time," Collazo said. "You see on the news all the time, but you don't think it could happen here until it does."
The nearby Hooters and Red Lobster were also on lockdown.
