A major manhunt was underway for suspects linked to the Paris massacre after three police officers were injured and a gunman went on the run during an anti-terror raid in Brussels.
Two men with Kalashnikov assault rifles opened fire on officers when they prepared to storm a suspected jihadi safehouse in the Belgian capital.
One of the gunmen fled in the chaos, prompting armed police to lock down the area.
Residents were ordered to stay indoors and a primary school close to the scene was cordoned off.
A helicopter flew overhead and police commandos were deployed. Snipers also surrounded the building where other suspects are believed to holed up.
