PARIS - It remains unclear how the suspected mastermind of the Paris attacks was killed.

Paris prosecutor Francois Molins says while he can confirm Abdelhamid Abaaoud is dead, they still do not know whether he blew himself up during raids in a suburb north of the city.

A statement released by the Paris prosecutor this afternoon states Abaaoud's body was found in a Saint-Denis apartment, riddled with bullets after a running battle with police - that included explosions and gunfire.

He was identified using papillary prints, which include patterns on fingers, palms and the soles of feet.

He's one of two people killed during a major operation in Saint-Denis that started at 4:30 yesterday morning and lasted several hours.

The Belgian national of Moroccan descent was named as the alleged ringleader days after Friday's deadly attacks.

A woman who blew herself up during yesterday's raids has been identified as Abaaoud's cousin.

Five police officers were slightly wounded and a police dog was killed.

One of the attackers remains at large.

Salah Abdeslam slipped through a road block while heading back to Brussels because his name was not on a wanted list at the time.
