LONDON (Web Desk) – ISIS has called for terror attacks on mainland Europe that will ‘paralyse’ the continent in the wake of the Brexit vote.

A message on the encrypted messaging service Telegram has reportedly urged ISIS affiliates to strike in both Berlin and Brussels following the historic vote.

A terror threat monitor revealed how fanatics had “expressed joy” over the economic turmoil and “fracturing” prevalent in Europe in the aftermath of Britain’s decision, the Daily Mail reported.

Last month, David Cameron – who made clear his intention to resign in October – appeared to suggest that ISIS would be “happy” if Britain voted to leave the EU in the referendum.

The Prime Minister had named ISIS mastermind Abu Bakr al-Baghdadi and Russian president Vladmir Putin as the main beneficiaries in the event of Britain leaving the EU.
