As Fox News reported:
Belgium’s prime minister said Sunday that the country’s capital is maintaining the highest terror alert for a sustained “serious and imminent” threat.
Schools and universities in Brussels will be closed, and the city’s subway will remain shut down, government officials decided at a meeting of the country’s National Security Council.
With one suspect in the Nov. 13 attacks in France last seen crossing into Belgium, officials in Brussels kept much of the city shut down during the weekend. Officials also recommended that sports competitions and all activities in public buildings be canceled, and malls and commercial centers closed.
