LONDON - British Prime Minister David Cameron has warned that Islamic State in Syria and Iraq (ISIS) is planning specific attacks against Britain and posed an existential threat to the West.
Mr Cameron was speaking after an Islamist gunman killed up to 30 British tourists in an attack last Friday that British politicians have described as the single worst assault on their nationals since the bombing of the London Underground in 2005.
"It is an existential threat because what is happening here is the perversion of a great religion and the creation of this poisonous death cult is seducing too many young minds," he told BBC radio yesterday. "There are people in Iraq and Syria who are plotting to carry out terrible acts in Britain and elsewhere and as long as ISIL (ISIS) exists in those two countries, we are at threat."
Britain's international terror threat is currently set at "severe", its second-highest level, which means an attack is "highly likely".
Police say they have launched one of their largest counter-terrorism operations in a decade after the murders in Tunisia.
Writing in The Daily Telegraph newspaper yesterday, Mr Cameron signalled that he wanted authorities to take a tougher line against Muslim extremists in Britain, to do more to challenge what he said were their unacceptable views.
"We must be more intolerant of intolerance - rejecting anyone whose views condone the Islamist extremist narrative," Mr Cameron wrote.
