Paris attacks 'ringleader' evidence emerges
The suspected ringleader of the Paris attacks was near the Bataclan theatre during a siege there, according to prosecutors.
Francois Molins said mobile phone data also showed Abdelhamid Abaaoud returned to cafes and restaurants targeted in the attacks.
He added there was evidence that Abaaoud was planning an attack on Paris's La Defense business district.
