ATTACK FEARS

Jean-Claude Juncker, head of the European Commission, the EU executive body, tweeted: "My thoughts are with the victims of the Strasbourg shooting, which I condemn with the utmost firmness. Strasbourg is an excellent symbol of peace and European Democracy. Values that we will always defend."

British Prime Minister Theresa May said she was "shocked and saddened."

Some 26,000 individuals suspected of posing a security risk to France are on the "S File" watchlist, of whom about 10,000 are believed to have been radicalised, sometimes in fundamentalist Salafist Muslim mosques, online or abroad.

European security agencies have feared for some time that Islamist militants who left Europe to fight for Islamic State in Syria and Iraq would return after the jihadist group's defeat, with the skills and motivation to carry out attacks at home.

Secular France has been grappling with how to respond to both homegrown jihadists and foreign militants following attacks in Paris, Nice, Marseille and beyond since 2015.

In 2016, a truck ploughed into a Bastille Day crowd in Nice, killing more than 80 people. In November 2015, coordinated Islamist militant attacks on the Bataclan concert hall and other sites in Paris claimed about 130 lives. There have also been attacks in Paris on a policeman on the Champs-Elysees avenue, the offices of satirical weekly publication Charlie Hebdo and a kosher store.

Almost exactly two years ago, a Tunisian Islamist rammed a hijacked truck into a Christmas market in central Berlin, killing 11 people as well as the driver.
