The FBI is investigating trips by the attacker who killed 14 people on Bourbon Street to Egypt and Canada in the months before the attack — as well as previous visits he made to New Orleans, plus stops at Texas gun stores in recent months, officials said.

Shamsud-Din Jabbar traveled to Cairo, Egypt in the summer of 2023, and to Ontario, Canada afterwards, an FBI official told reporters Sunday. He also made a pair of trips to New Orleans last fall, in the months before the attack, officials said.

An ATF agent described explosive material found with Jabbar, saying the materials showed he was inexperienced in the construction and use of explosives.

Officials have said Jabbar was inspired by the Islamic State terror group, though they say the precise nature of his relationship to the group remains under investigation.

The FBI still believes Jabbar acted alone in plotting the New Year’s Day attack, officials said.
