Strasbourg, France (CNN)More than 700 police and military officers across three European countries have joined the hunt for a lone gunman who killed at least two people and wounded 13 others at a Christmas market in the French city of Strasbourg, Tuesday, in what authorities have called a terrorist attack.
The suspect, identified as 29-year-old Cherif Chekatt, has an extensive criminal background that includes 27 convictions in France, Germany, and Switzerland, mainly for acts of robbery and violence.
Swiss police said they were “on alert” and in close contact with their French counterparts, while Germany’s federal police said they were conducting intensive search efforts on roads and railways, which could cause delays for people crossing the border. French Anti-terror police have also now joined the search, as efforts stretch into a second day.
