As police in Belgian continued to dismantle a terror cell believed to have carried out the Paris and Brussels attacks with new arrests, authorities said there may be other active terrorist groups in the country.

His comments came as Mohamed Abrini was positively identified as the “man in the hat” connected to the Brussels airport bombing last month. Abrini was one of four suspects charged Saturday with “participating in terrorist acts” linked to the deadly suicide bombings that killed 32 people and wounded 270 others at the airport and at the city’s Maelbeek subway station.
