Friday has been a heartbreaking day in Santa Fe, Texas. Up to 10 people were killed after at least one gunman opened fire in Santa Fe High School, according to multiple reports.
A male, believed to be a student, has been arrested, and another student has been detained, police said.
"It is with great sadness that I stand here to share with you that we experienced an unthinkable tragedy at our high school this morning," Santa Fe Independent School District Superintendent Leigh Wall said in a statement posted to Twitter. "We are grieving the loss of members of our SFISD family."
Explosives were found on school property and the surrounding area, the school district said, warning community members to "be on the lookout for suspicious packages and anything that looks out of place."
KTRK-TV in Houston published dispatch audio, via Broadcastify, of police learning about the school shooting. It paints a frightening, tragic scene.
"More shots fired, additional shots fired," someone says over the audio, posted by KTRK. At some point in the recording, listeners can hear a loud noise that sounds like gunfire. "We're coming out the front door," someone says over the dispatch, while another person notes there is still active gunfire.
Students described trying to escape amid the gunfire.
"We were all standing [outside], but not even five minutes later we started hearing gunshots," Angelica Martinez, a 14-year-old student at Santa Fe High School, told CNN. "And then everybody starts running, but, like, the teachers are telling us to stay put, but we're all just running away."
President Donald Trump said the federal government was sending resources to Texas.
"We're closely monitoring the situation, and federal authorities are coordinating with local officials," he told reporters. "This has been going on too long in our country."
