A number of British Muslims have joined Isis extremists in Iraq and Syria

SOME of Britain’s most influential imams have condemned British Muslims fighting alongside Isis extremists in Iraq and Syria.

They have issued a fatwa, or religious decree, describing them as “heretics”.

The fatwa ”religiously prohibits” would-be British jihadists from joining “oppressive and tyrannical” Isis, also known as Islamic State. The imams order all Muslims to oppose Isis’s “poisonous ideology” , especially when it is promoted within Britain.

The fatwa, the first of its kind issued by British Muslim scholars, follows the elevation of Britain’s terror threat from substantial to severe, meaning an attack is “highly likely”.

Senior officials revealed last night that the prime minister would announce plans tomorrow for laws to prevent British jihadists fighting in Iraq and Syria from re-entering Britain. Passports of UK
