"I am left heartbroken by the massacre in the elementary school in Texas," Francis said, according to Reuters. "I pray for the children, for the adults killed, and for their families."

He then shifted his focus to the gun industry, saying, "It is time to say 'enough' to the indiscriminate trafficking of weapons. Let us all make a commitment so that tragedies like this cannot happen again."

Francis has been a critic of the firearms industry for years and has claimed that spending money on weapons "sullies the soul."

The total number of people killed in the shooting has risen to 21 as of Tuesday evening. Several others were injured or hospitalized. The gunman, identified as Salvador Ramos, an 18-year-old high school student from Uvalde, was killed by law enforcement at the school after a Border Patrol agent entered the building and opened fire on Ramos. The agent was wounded in the battle.

Ramos displayed violent tendencies and had a troubled home and school life, according to reports. Police believe Ramos shot his grandmother before the mass shooting at the elementary school. Authorities have not released a motive for the shooting.

President Joe Biden was briefed on the shooting and delivered remarks on it Tuesday evening. Biden also ordered the flag at the White House and other government and military buildings to be lowered to half-staff as a "mark of respect for the victims of the senseless acts of violence."
