At least 19 students and two adults were killed in a mass shooting at an elementary school in Uvalde, Texas, on Tuesday, public safety officials said.
Texas Gov. Greg Abbott said that the gunman, an 18-year-old local resident, is dead. Authorities say he shot his grandmother before heading to the school. She was listed in critical condition late Tuesday.
The massacre comes 10 days after 10 people were killed in a mass shooting at a Buffalo, N.Y., grocery store.
"I am sick and tired of it," President Biden said in a televised address to the nation. "We have to act."
