Brussels on full security alert, metro closed

Brussels has been placed on its highest level of security alert after what officials describe as a “serious and imminent threat”.

The Belgian capital and region have moved up to level four after intelligence suggested the threat of a “Paris-style” attack involving weapons and explosives.

The city’s metro system will remain closed for both Saturday and Sunday.

Police and soldiers are out in force on the streets.

The focus is on protecting public areas like stations and squares.

The government’s crisis centre has warned the public to avoid crowded areas where people are likely to gather.
