ISIS threatens an attack on Britain so horrific it will 'turn children's hair white' [VIDEO]
ISIS have threatened an attack on Britain so horrific it will 'turn children's hair white' as latest video warns of further outrages across the continent.
The terror group has warned the UK will suffer 'the lion's share' of the slaughter it intends to wield in Europe, according to its Arabic language newspaper, al-Naba.
However, in a video released on Saturday, the millitants suggest it is Spain which will come under the strongest attack as the West is forced to 'pay dearly' for having crushed Muslim rule in Andalusia - more than 500 years ago.
The attack on Britain is fueled by the more recent decision to bomb ISIS strongholds in Syria, an article which eulogised evil London murderer Mohammed Emwazi said.
According to the Sunday Times, the attack will be so dreadful 'it will turn the children's hair to white'.
This is thought to refer to a doomsday prophesy in the Koran.
