Pope Francis offered his condolences after 15 people were killed in New Orleans when a U.S. Army veteran drove a pickup truck with an Islamic State flag into a crowd celebrating the New Year.

The pope sent a condolence message to New Orleans Archbishop Gregory Aymond on Jan. 2 offering prayers for the souls of the deceased as well as the healing and consolation of the injured and bereaved. 

“His Holiness Pope Francis was deeply saddened to learn of the loss of life and injury caused by the attack that took place in New Orleans,” said the message sent on the pope’s behalf by Vatican Secretary of State Cardinal Pietro Parolin.

“In assuring the entire community of his spiritual closeness, His Holiness commends the souls of those who have died to the loving mercy of Almighty God and prays for the healing and consolation of the injured and bereaved. As a pledge of peace and strength in the Lord, the Holy Father sends his blessing.”

The New Orleans attack is being investigated as an act of terrorism by the FBI, which believes that the driver, Shamsud-Din Jabbar, 42, did not act alone. Jabbar was killed in a shootout with police after driving a truck with an explosive device into a crowd of people celebrating the new year in New Orleans’ French Quarter three hours after midnight.

President Joe Biden said Wednesday evening that the driver had posted videos to social media saying that he was inspired by the Islamic State group in the hours before what Biden called the “heinous act.”

About 30 other people were injured by the New Orleans attack, including two police officers wounded by gunfire from the suspect, according to Reuters. 

Among the 15 victims were a mother of a 4-year-old, an 18-year-old aspiring nurse from Mississippi, and a student-athlete who was visiting home for the holidays.

“Our prayers go out to those killed and injured in this morning’s horrific attack on Bourbon Street,” Aymond said in a brief statement released on the archdiocese’s website.

“This violent act is a sign of utter disrespect for human life,” he said. “I join with others in the Roman Catholic Archdiocese of New Orleans in offering prayerful support to the victims’ families. I give thanks for the heroic duty of hundreds of law enforcement and medical personnel in the face of such evil.”

FBI officials have said they are also looking for any links with a separate incident in Las Vegas on New Year’s Day in which one person was killed and seven people were injured when a rented Tesla Cybertruck exploded into flames outside of the Trump International Hotel.
