Terror attacks in Paris on November 13

The suspects were in touch with someone using two mobile phones in Belgium, the newspaper Het Nieuwsblad wrote on Monday. A text message was sent from the attackers to one phone in Belgium saying that "action" was being taken, according to the newspaper De Standaard. Investigators believe that the person who was in possession of the mobile phones may have coordinated the Paris attacks. Belgian police carried out a search in the centre of Brussels on Sunday evening in connection with the hunt for that person. Two men were taken into custody for questioning, but they are not believed to be the suspect with the phones.
