An eyewitness has told local media that there were a dozen worshippers in the mosque when a man attacked with a petrol bomb. An imam died as a result of smake inhalation, and another person was injured. Azzedine Laghmish told Belgium's national broadcaster RTBF:
A dozen worshippers were waiting to pray when someone entered with a bag. Inside there was a container full of petrol which he threw into the centre of the room. The fire took hold very quickly. The imam tried to put it out but he found himself stuck in a room.
