BRUSSELS (Reuters) - The Brussels metro and schools reopened on Wednesday as the Belgian capital edged back to normal after a four-day security lockdown but the hunt went on for militants police fear may mount a Paris-style mass attack.
Troops and armoured vehicles outside reopened underground stations -- about half of the network remains closed -- and police outside schools provided a reminder of the threat the government said was so imminent that it raised its alert level on Saturday in Brussels to the maximum, where it remains.
