London, Feb 1: The Islamic State (ISIS) terror group has warned Britain of an attack more severe than the Paris strikes, saying the country will receive the "lion's share" of the slaughter for its "declaration of war against Muslims".
In the latest edition of its Arabic newspaper 'al-Naba' (The News), ISIS warns that the UK should be prepared for an attack more severe than in Paris last November which claimed 130 lives.
According to 'The Sunday Times', the article eulogises Mohammed Emwazi, the British national dubbed Jihadi John who was killed by a US drone strike.
It said "his words will never die" and that his message of slaughter did not end "with the blood of the soldiers of the caliphate who sent it to France in their own special way".
Britain will receive the "lion's share" of the slaughter "in response to its declaration of war against the Muslims", the group said in reference to last month's UK Parliament vote on airstrikes against ISIS in Syria.
An attack on Britain will be so severe, it claims, "that it will turn children's hair to white". The warning refers to a Quranic verse outlining the horrors of the Judgement Day.
ISIS had released a video last week that featured nine of the Paris attackers, including ringleader Abdelhamid Abaaoud.
By examining the montage frame by frame, 'The Sunday Times' has identified a string of potential targets, includingBuckingham Palace and the National Gallery in central London.
A palace spokesperson said, "We never comment on security matters."
