The city of Brussels and its suburbs remain on high alert as police searched for suspects in the Paris terrorist attacks.
Belgian Prime Minister Charles Michel said Sunday that the area would stay at the highest terror alert level—level 4, which means a terrorist threat is “imminent and close by”—for now, according to Belgium’s national Crisis Center. Schools and universities in the Brussels region will be closed on Monday.
Belgian authorities issued the alert on Sunday. They dispatched heavily armed soldiers to patrol the region and advised citizens to stay away from shops, train stations, airports, and other public spaces. They also closed the Brussels metro, which will not reopen Monday. The Brussels region has a population of about 1 million.
The rest of Belgium will remain at a threat level of 3 (“possible and likely”). Officials had raised the countrywide alert from level 2 to level 3 several days after terrorists killed 130 people at a concert hall, outside a stadium, and in busy streets in the French capital on November 13.
Belgian and French police have carried out dozens of raids in Brussels, Paris, and elsewhere in search of suspects in the deadly siege, the worst violence on French soil since World War II. They are looking for Salah Abdeslam, a 26-year-old Brussels resident who was last seen headed for the Belgian border hours after the siege in Paris. The suspected organizer of the attacks, Abdelhamid Abaaoud, a Belgian citizen, was killed during a French police raid Wednesday in the Paris suburb of St. Denis. Seven assailants died in the Paris attacks, including Abdeslam’s brother, Ibrahim, who detonated his suicide belt outside of a cafe.
