PARIS/BRUSSELS (Reuters) - An investigation into the Nov. 13 attacks in Paris widened on Tuesday when French prosecutors said a man who provided lodging to the suspected ringleader must have known of a militant plot, and Belgium issued a warrant for a new suspect.

Painting a chilling picture of ringleader Abdelhamid Abaaoud, the Paris prosecutor said that after dropping off the gunmen and suicide bombers at the cafes and bars where the attacks were to take place, he later returned to the scene while the killing spree was in full swing.
