Paris (Agencies): At least four people were killed and eleven others were wounded after a lone gunman opened fire near a Christmas market in the city of Strasbourg on Tuesday evening.
Interior Minister Christophe Castaner said the gunman was known to security services, and the local prefecture said he had previously been identified as a danger to security.
People in the city's Neudorf area and Etoile park were told to stay where they were as officers hunted the shooter on the ground and from the air.
The European Parliament, which is sitting in Strasbourg this week, was put into lockdown.
The Christmas market was being held amid tight security this year, with unauthorised vehicles excluded from surrounding streets during opening hours and checkpoints set up on bridges and access points to search pedestrians' bags.
President Emmanuel Macron was informed of the shooting and was being updated as events unfurled, an Elysee Palace official said. Castaner was on his way to Strasbourg, which lies on the border with Germany.
A spokesman for the European Parliament said the building had been shut down and staff ordered to stay inside.
