Police forces in France will be patrolling the streets of France until ISIS is destroyed and no longer a threat to the world.
French Prime Minister Manuel Valls warned that Europe’s migration crisis was now putting the European Union itself at grave risk.
German Chancellor Angela Merkel is due to hold talks with Turkish Prime Minister Ahmet Davutoglu in Berlin.
EU countries hope Turkey will help to control the flow of migrants reaching the EU from Syria and other conflict zones.
Mr Valls said France was “at war”, which meant “using all means in our democracy under the rule of law to protect French people”. “As long as the threat is there, we must use all the means,” he said, adding that it should stay in place “until we can get rid of Daesh”, using an acronym for IS.
“In Africa, in the Middle East, in Asia we must eradicate, eliminate Daesh,” he said. “It is a total and global war that we are facing with terrorism,” he added. “The war we are conducting must also be total, global and ruthless.”
