Belgian Prime Minister Charles Michel has announced that the capital is on its highest level of alert after receiving information about being targeted for a possible attack like the one in Paris last week.

Prime Minister Michel explained that the warning suggested "several individuals with arms and explosives could launch an attack... perhaps even in several places."

As part of the increased security measures, the metro is closed until tomorrow and citizens are warned to stay away from crowds, including at concerts and shopping centers. The government has also recommended canceling soccer games and other large events.

The rest of the country is at a "serious" level of security alert. The conditions will be reexamined on Sunday.

Several of the terrorists who attacked Paris previously lived in Brussels and authorities believe that the prime surviving suspect, Salah Abdeslam, returned to Belgium.
