It is the deadliest attack by ISIS on the West in several years. But still, almost a week later, the group also known as Islamic State has yet to issue its trademark claim of responsibility for the horrific New Year’s violence in New Orleans.

Shamsud-Din Jabbar appears to have been inspired by the Islamic State, Biden says. The U.S.-designated terrorist group once controlled swaths of Syria and Iraq.

Recordings and interviews detail Shamsud-Din Jabbar’s growing discontent with American society and increasing isolation even within his local Muslim community.

The New Year’s Day terror attack in New Orleans is a warning that ISIS, and foreign terror groups in general, still have influence in the United States, the Pentagon’s civilian head of special operations said Tuesday.

Family members and friends have begun identifying the 14 people who died in the truck-ramming attack early Wednesday morning on Bourbon Street in New Orleans.

The 42-year-old U.S. Army veteran responsible was a Houston resident, who, prior to striking, pledged his allegiance to ISIS.
