BRUSSELS: Belgium raised the alert status for its capital Brussels to the highest level on Saturday, shutting the metro and warning the public to avoid crowds because of a “serious and imminent” threat of an attack.
A week after the Paris attacks carried out by Islamic State militants, of whom one suspect from Brussels is at large and said by authorities to be highly dangerous, the city was placed on the top level “four” in the government’s threat scale after a meeting of top ministers, police and security services.
“The advice for the population is to avoid places where a lot of people come together like shopping centres, concerts, events or public transport stations wherever possible,” a spokesman for the government’s crisis centre said.
Belgian Prime Minister Charles Michel declined to give the reason why the authorities raised the alert level but told a news conference the government would review the security situation on Sunday afternoon.
The metro system would remain closed until then, in line with the recommendation of the crisis centre, he said.
The crisis centre website said it was calling on local authorities to cancel large events, urge people to avoid crowds, postpone soccer matches, close the Brussels metro for the weekend and stepping up the military and police presence.
Suspected militant Salah Abdeslam, 26, returned home to Brussels from Paris after the attacks, when his elder brother Brahim blew himself up at a cafe.
Fears of the risk he still poses prompted the cancellation last week of an international friendly soccer match in Brussels against Spain. The crisis centre said weekend games in the top two professional divisions should now be postponed.
The alert level for the whole country was raised following the Paris attacks to level three out of four, implying a “possible or probable” threat. Previously, only certain sites, such as the U.S. embassy, were at level three.
Belgium, and its capital in particular, have been at the centre of investigations into the Paris attacks – which included suicide bombers targeting a France-Germany soccer match – after the links to Brussels emerged. Three people detained in Brussels are facing terrorism charges.
French authorities have said the attacks were planned in Brussels by a local man, Abdelhamid Abaaoud, 28, who fought for Islamic State in Syria and was killed in the siege of an apartment in the Paris suburb of St. Denis on Wednesday.
Salah Abdeslam, who was from the same Brussels neighbourhood of Molenbeek and is said by officials to have known Abaaoud in prison, was pulled over three times by French police but not arrested as he was driven back to Brussels early last Saturday by two of the men now in custody.
As well as Abdeslam’s brother, a second man from Molenbeek, Bilal Hadfi, was also among the Paris suicide bombers.
Belgian Interior Minister Jan Jambon told reporters he wanted a register of everyone living in Molenbeek because it was not clear at present who was there, with authorities conducting door-to-door checks of every house.
“The local administration should knock on every door and ask who really lives there,” Jambon said.
Soldiers are already on guard in certain parts of Brussels, including at the institutions of the European Union headquartered in the city.
Brussels is also home to the headquarters of NATO.
The last time any part of the country was put on maximum alert was in May 2014 when a gunman shot dead four people at the Jewish Museum in Brussels. At that time, Jewish schools, synagogues and other institutions were put on level four.
The capital as a whole was last at the level four for about a month at the end of 2007 and the start of 2008, when authorities intercepted a plot to free convicted Tunisian Nizar Trabelsi. Brussels’ traditional New Year fireworks display was cancelled.
Trabelsi was sentenced in Belgium in 2003 to 10 years for attempting to blow up a Belgian military base that houses U.S. soldiers. He was extradited to the United States in 2013.
