BRUSSELS—Heavily armed police and soldiers patrolled key intersections, subways were closed and many stores shut their doors in Belgium’s capital Saturday as the government warned of a threat of Paris-style attacks. At least one suspect from the deadly Paris attacks is at large and was last seen crossing into Belgium.
Prime Minister Charles Michel said the decision to raise the threat alert to the highest level was taken “based on quite precise information about the risk of an attack like the one that happened in Paris ... where several individuals with arms and explosives launch actions, perhaps even in several places at the same time.”
The Belgian Federal Prosecutor’s office said Saturday several weapons were discovered during the search of the home of one of three people arrested in connection with the Paris attacks, but said no explosives were found.
Authorities across Europe, the Mideast and in Washington are trying to determine how a network of primarily French and Belgian attackers with links to Islamic extremists in Syria plotted and carried out the deadliest violence in France in decades—and how many may still be on the run.
