French authorities have filed terror charges against two suspects linked to ISIL, the terror group that is responsible for the massacre of 130 people in Paris last November. A 29-year-old Algerian and 35-year-old Pakistani have been charged with "criminal conspiracy with terrorists".

The two were turned in earlier Friday by Austrian authorities. Investigators believe they travelled to the Greek island of Leros in October on a boat full of refugees alongside two others that took part in the November attacks.

Those two, thought to be Iraqis, blew themselves up outside the Stade de France stadium, one of a series of brazen assaults by around 10 people which took place in the French capital. 

The Algerian and Pakistani suspects, however, were held up and detained by Greek authorities as they had fake Syrian passports.

They then followed the main migrant trail and made it to the western part of Austria at the end of November -- after the Paris attacks.

Austrian police commandos then arrested them in December at a migrant centre. Austrian police added that during the entire journey and up until their arrest, the men remained in constant contact with the terror group "Islamic State".
