The man who provided lodging for the presumed mastermind of the Paris attacks will go before an anti-terrorism judge on Tuesday as the hunt for suspected gang member Salah Abdeslam, Europe's most wanted fugitive, entered its 11th day.
Frenchman Jawad Bendaoud said before he was detained by police last Wednesday that he had been asked to put up two people for three days in an apartment in St. Denis north of Paris, but he had no idea one of them was the attackers' ringleader.
It was in this flat that Abdelhamid Abaaoud, the suspected leader of the attacks claimed by Islamic State, died during a police raid along with Hasna Aitboulahcen, a woman believed to be his cousin, and an as yet unidentified third person.
Under French counter-terrorism laws, Bendaoud must be charged or released on Tuesday. The Paris Prosecutor is due to hold a news conference at 6.30 p.m. (1730 GMT), though the prosecutor's office has said Bendaoud will go before a judge.
The Paris attacks that killed 130 people on Friday, Nov. 13, at the national sports stadium, a concert venue and bars and restaurants in heart of the capital, shocked a city already struck by Islamist gunmen in January.
Since the killings, France has moved its flagship Charles de Gaulle aircraft carrier into the eastern Mediterranean to step up its bombardments of Islamic State targets in Syria and Iraq.
President Francois Hollande is also trying to rally support this week for a more coordinated international campaign to destroy the militant group. He is due to meet President Barack Obama later on Tuesday and to visit Moscow on Thursday.
As millions of Americans prepare to travel for the U.S. Thanksgiving holiday on Thursday, the U.S. State Department issued a global alert of "increased terrorist threats".
The agency said on Monday current information suggested that Islamic State, al-Qaeda, Boko Haram, and other groups continued to plan attacks in multiple regions.
