Two people were killed and multiple children were hospitalized Tuesday during a shooting at an elementary school in Uvalde, Texas, which was placed on lockdown as law enforcement responded to an “active shooter” who police say is now in custody.

The Texas Department of Public Safety and Uvalde Mayor Don McLaughlin told Fox News that the shooter – who ran to Robb Elementary School – had become barricaded inside. Uvalde Memorial Hospital confirmed that two people were brought to the hospital deceased.

Thirteen children were taken to the facility via ambulance or bus for treatment.

“There is an active shooter at Robb Elementary. Law enforcement is on site,” the school posted on Facebook shortly after shots rang out. “Your cooperation is needed at this time by not visiting the campus.”

No information on the suspected shooter or the victim was released. The school is located 80 miles west of San Antonio.
