An 18-year-old gunman opened fire on Tuesday at a Texas elementary school, killing at least 19 children as he went from classroom to classroom, officials said.

This is deadliest school shooting in nearly a decade and the latest gruesome moment for a country scarred by a string of massacres.

The attacker was, however, killed by law enforcement.

The death toll also included two adults, authorities said. Gov. Greg Abbott said one of the two was a teacher.

The assault at Robb Elementary School in the heavily Latino town of Uvalde was the deadliest shooting at a U.S. school since a gunman killed 20 children and six adults at Sandy Hook Elementary in Newtown, Connecticut, in December 2012.

Hours after the attack, families were still awaiting word on their children.

Outside the town civic center, where families were told to await news about their loved ones, the silence was broken repeatedly by screams and wailing. “No! Please, no!” one man yelled as he embraced another man.

“My heart is broken today,” said Hal Harrell, the school district superintendent. “We’re a small community, and we’re going to need your prayers to get through this.”

According to AFP, Adolfo Cruz, a 69-year-old air conditioning repairman, was still outside the school as the sun set, seeking word on his 10-year-old great-granddaughter, Elijah Cruz Torres.

He drove to the scene after receiving a terrifying call from his daughter shortly after the first reports of the shooting. He said other relatives were at the hospital and the civic center.

Waiting, he said, was the heaviest moment of his life.

“I hope she is alive,” Cruz said.

The attack came just 10 days after a deadly, racist rampage at a Buffalo, New York, supermarket that added to a yearslong series of mass killings at churches, schools and stores.

And the prospects for any reform of the nation’s gun regulations seemed as dim, if not dimmer, than in the aftermath of the Sandy Hook deaths.

But President Joe Biden appeared ready for a fight, calling for new gun restrictions in an address to the nation hours after the attack.

Biden said: “As a nation we have to ask, when in God’s name are we going to stand up to the gun lobby? When in God’s name are we going to do what has to be done?

“Why are we willing to live with this carnage?”

Many of the wounded were rushed to Uvalde Memorial Hospital, where staff members in scrubs and devastated victims’ relatives could be seen weeping as they walked out of the complex.

Officials did not immediately reveal a motive, but they identified the assailant as Salvador Ramos, a resident of the community about 85 miles (135 kilometers) west of San Antonio.

Law enforcement officials said he acted alone.
