A massive explosion rocked multiple buildings in the Belgium city of Antwerp on Monday, reports said.

The blast knocked down at least one building and multiple people were reported injured, according to the UK’s Metro newspaper.

Emergency vehicles could be seen racing to the scene in video posted on social media.

It was unclear what the cause of the blast was.

The buildings were about four stories high and one housed a pizzeria on the first floor.
