Three dead, several injured in Utrecht shooting

At least three people have been killed and several others injured in a shooting in the central Dutch city of Utrecht.

Police have cordoned off a square near a tram station outside the city centre, and are considering the possibility of a "terrorist motive". 

According to reports, the gunman opened fire on a tram before fleeing the scene.

Security measures have been stepped up across the city while counter-terrorism forces search for the attacker.

They earlier surrounded a house near the 24 Oktoberplein junction where the tram attack took place, but no arrests seem to have been made.
