Belgium raises terror alert to highest level in Brussels

Belgium raised its terror alert level to the highest level in the capital Brussels on Saturday, warning of an "imminent threat" in a statement from the OCAM national crisis centre.

"Following our latest evaluation... the centre has raised its terror alert to level 4, signifying a very serious threat, for the Brussels region," said the statement, which comes a week after the Paris attacks left 130 dead.

"The analysis shows a serious and imminent threat requiring specific security measures as well as detailed recommendations to the population," OCAM, which is part of the Belgian Interior Ministry, said in the statement.
