Internet giants will face increased pressure to tackle online extremism as European leaders were expected to back a UK -led drive for tougher internet regulation.
Foreign Secretary Boris Johnson will lead calls to ensure there is “no safe space for terrorists” to plot attacks and share radical material online when he attends a meeting of EU foreign ministers in Luxembourg on Monday.
Speaking ahead of the meeting, Mr Johnson said: “We are pushing back Daesh militarily, but the threat we face is evolving rather than disappearing as they lose ground in Iraq and Syria.
“There should be absolutely no safe space for terrorists plotting attacks, radicalising young people and encouraging others to carry out violence in the name of an obscene ideology.
Terrorism affects us all and we need a common approach to ensure the problem gets solved, and at a much faster pace than we are seeing right now."
