ISIS has claimed responsibility for the depraved attack in London Bridge as chilling video shows three jihadis calmly strolling past a pub while in the midst of the van and knife rampage that killed eight and critically injured 21.

The twisted killers are seen calmly walking through Borough Market moments before they launched a stabbing attack on pubgoers while shouting "this is for Allah", having already driven a van into crowds.

Terror group ISIS has claimed responsibility for the mass killing more than 24 hours after the atrocity through their affiliated news agency Amaq.

Despite the warped death cult's claims, Amaq recently claimed that an arson assault on a casino in Manila was ISIS-related. But CCTV footage released shortly after suggested the incident was a botched robbery and not terror related.

On Saturday on London Bridge, a three-strong terrorist gang wearing fake suicide vests were shot dead by armed police after inflicting eight minutes of terror on those enjoying a summer's evening in the capital, killing seven and injuring 48 - with 21 still critical.

The PM delivered a firm warning to those who harbour extremists in what looked like a turning point in terror policy today after the latest terror attack struck in the heart of London.

Following the third terrorist attack in three months Mrs May defiantly confirmed Thursday's General Election will go ahead and issued a warning to jihadis and those who harbour them as she said "things need to change".

After chairing a Cobra meeting she said: "It is time to say enough is enough. Everybody needs to go about their lives as they normally would. Our society should continue to function in accordance with our values.

"But when it comes to taking on extremism and terrorism, things need to change.

“While we have made significant progress in recent years there is, to be frank, far too much tolerance of extremism in our country.

“So we need to become far more robust in identifying it and stamping it out - across the public sector and across society.

“That will require some difficult and often embarrassing conversations, but the whole of our country needs to come together to take on this extremism."
