German police on the French border were on high alert on Wednesday (December 12) as the hunt for a gunman continued who killed three people and wounded a dozen others at a Christmas market in the eastern French city of Strasbourg.
Policemen carrying machine guns set up a roadblock at the Iffezheim crossing across the river Rhine, looking at passengers in passing vehicles.
Police identified the suspect as Strasbourg-born Cherif Chekatt, 29, who is on an intelligence services watch list as a potential security risk.
"The hunt continues," Deputy Interior Minister Laurent Nunez said on France Inter radio.
Asked whether the suspect might have left France, he said: "That cannot be ruled out."
