BRUSSELS (Reuters) - Schools and much of the Brussels metro system reopened on Wednesday as the Belgian capital started to return to normal after four days of lockdown, but troops on the street were a reminder it remains on the highest alert.

With police still hunting a local man who is a prime suspect in the Nov. 13 attacks in Paris, along with up to 10 others authorities fear could be planning further violence, the government only plans to review the alert status next week.
