More details are coming out about the man behind the attack in the French city of Nice last week.
French prosecutors now say that Mohamed Lahouaiej Bouhlel had shown signs of radicalization in recent months. But it's still unclear whether he had any direct connection with ISIS. The terrorist group later claimed to be behind the attack.
So what do we know about the connection?
"Very little," says Mark Mazzetti. He co-wrote a piece for the New York Times that examines what it means, exactly, to be radicalized.
"At this point it's really unclear whether this is something they are just claiming credit for because it helps their cause, or whether he was inspired at the last moment or radicalized at the last moment. There's really not a lot of detail at the moment," he says.
Mazzetti says if you take ISIS out of it all you see from the attacks of the last year are a collection of deranged individuals. "They would have carried out the attack anyway for their own cause and doing it in the name of ISIS might give them some 11th hour justification," he says.
