RABAT, Morocco -- Moroccan police arrested a Belgian man of Moroccan descent linked to the Islamic State group and who had a "direct relationship" to attackers who carried out the Paris attacks just over two months ago, the Interior Ministry said Monday.

The man had traveled to Syria with one of the Paris suicide bombers, where he received military training and built relationships with IS field commanders, "including the mastermind" of the Paris attacks, and others who threatened attacks in France and Belgium, the ministry said in a statement.

The statement identified the suspect only by the initials J.A. and didn't explain his suspected relationship to the Paris attackers. Several of the Islamic extremists who targeted a Paris rock concert, stadium and cafes had Moroccan origins and links to Belgium.

The attacks Nov. 13 killed 130 people.

The ministry said in a statement the man was arrested Friday in the town of Mohammedia, near Casablanca, after traveling through Turkey, Germany, the Netherlands and Belgium. It said the suspect is under investigation.

Belgian prosecutors didn't comment on the arrest.

At least one of the Paris attackers remains at large.

Morocco has emerged as a key ally for European investigators trying to piece together the geography of the Nov. 13 attacks.

The head of Morocco's Central Bureau of Judicial Investigations, dubbed the "Moroccan FBI," said in a recent interview his country put French and Belgian police on the trail of the network behind the Paris attacks.

Several of the attackers lived in the Brussels neighborhood of Molenbeek, home to numerous Belgians of Moroccan descent.
