A shooting in the French city of Strasbourg sparked a major security operation around a famous Christmas market on Tuesday. At least three people were killed and at least a dozen others wounded.
The French Interior Ministry called on the public to remain indoors and local authorities called on residents to follow police instructions.
"Our security and rescue services are mobilized," Interior Minister Christophe Castaner said.
Local authorities tweeted for the public to "avoid the area of the police station," which is close to the Strasbourg Christmas market in eastern France.
The manhunt is on for the suspect. Police know who they're looking for.
Investigators are on the lookout for a 29 year-old, who officials say was on a terrorism watch list.
When police arrived at his home, they found explosives, though nothing was detonated.
France has been hit by several extremist attacks in recent years, including the 2015 Paris shootings, which killed 130 people and wounded hundreds.
There was also a truck attack in Nice that killed dozens in 2016.
Some Strasbourg residents reported on social media that they had heard gunfire in some parts of the city centre.
President Emmanuel Macron adjourned a meeting at the presidential palace on Tuesday night to be able to monitor the events. His office said Strasbourg, about 500 kilometres east of Paris, is the seat of the European Parliament and on the border with Germany.
