Media reports indicated that a US male citizen had intentionally driven a pick-up truck into a crowd of people celebrating the new year in the city’s French quarter shortly after 3am local time.

The 42-year-old suspect was killed in a police shootout that injured two officers. His potential allegiance to ISIL extremists is under investigation after a flag of the terrorist organization and improvised explosives were found in the rented vehicle and in other locations nearby, according to the FBI.

“The Secretary-General strongly condemns the attack in New Orleans, where a driver struck a crowd gathered to celebrate the New Year, reportedly killing at least 15 people and injuring over 30 others,” said his Associate Spokesperson, Florencia Soto Nino-Martinez.

“He extends his condolences to the families and loved ones of those who lost their lives and to the Government and people of Louisiana and the United States. He also wishes a swift recovery to those persons injured.”

The US authorities are also investigating possible links between the outrage and a deadly vehicle explosion in Las Vegas on Wednesday morning.

Reports indicated that a Tesla Cybertruck exploded near the entrance of Trump International Hotel on New Year’s Day. Police said that the driver was killed and seven others were injured when a combination of fireworks, gas tanks and camping fuel was detonated.
