Good morning.

Terror struck the busy French Quarter of New Orleans at about 3.15am on New Year's Day, as a vehicle flying an Islamic State (IS) flag was driven into a crowd of people on Bourbon Street - killing at least 15 and injuring 30.

What do we know about the suspect? The 42-year-old Texas man accused of the crime, Shamsud-Din Jabbar, is a US citizen and served in the US army for 13 years, including a deployment to Afghanistan from 2009-10. Law enforcement officials said they were looking for accomplices, suspecting Jabbar did not act alone.
