The killer driver who mowed down New Orleans revelers in a deadly New Year’s Day terror attack has been pictured for the first time in a photo obtained exclusively by The Post.

Shamsud Din Jabbar, 42, was identified by law enforcement sources as the suspect behind Wednesday’s massacre.

He was shot and killed in a firefight with cops just moments after he plowed into crowds on the famed Bourbon Street just after 3 a.m. — leaving 10 dead and 35 injured.

Jabbar had what appeared to be an Islamic caliphate flag — similar to an ISIS flag — on the truck at the time of the attack, sources said.
