Two people are dead and up to 11 more are injured, including in critical condition after a gunman opened fire on a Christmas market in Strasbourg, France.

French police said the Strasbourg shooting suspect is known to authorities, and on a terrorist watch list; suspect remains at large; everyone in the Neudorf area warned to stay indoors.

French prosecutors have opened a terror case into the shooting.

According to an eyewitness, there were gunshots and people were running everywhere for at least 10 minutes.

Reuters reported:

A lone gunman shot dead at least two people and wounded 11 others near a Christmas market in the city of Strasbourg on Tuesday evening before fleeing, police said. The motive was not immediately clear but, with France still on high alert after a wave of attacks commissioned or inspired by Islamic State militants since early 2015, the counter-terrorism prosecutor opened an investigation. 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.
