'London terror attack is a classic Al-Qaeda or Isis-style attack' - security expert

An attack in London which killed seven people and left 48 injured, a number of whom are critical, looks like a "classic Al-Qaeda and/or IS-style attack", according to an anti-terrorism consultant.

The attack, carried out by three people in the London Bridge and Borough Market area of London on Saturday night, is the second terror incident to hit the UK in just two weeks.

According to witnesses, three people in a white van drove erratically across London Bridge striking people, before parking up and proceeding to run through Borough Market area, stabbing numerous people.

The perpetrators were apprehended within eight minutes of emergency services receiving the first phone-call.

Anti-terrorism consultant Chris Hunter told Sky News it's "early days" regarding suspects, but he believes the attack has all the characteristics of an extremist attack.

"It's a classic Al-Qaeda and/or Isis-style attack," Mr Hunter said.

"Obviously it's early days to determine the attackers and what they were representing... it was a very cowardly attack.

"Police were at the scene within minutes.

"There were very good skills carried out by everybody.

"I don't like the term lone wolf," he continued.

"It suggests there's something special about them. The reality is they're evil.

"They look for vulnerabilities, they look to identify maximum publicity.

"They look to identify weaknesses in current security incidents.

"They bring them all together."

Meanwhile, London Mayor Sadiq Khan said Britain's national parliamentary election on Thursday should not be postponed following the attack.

Khan said Londoners would see an increased police presence in the city after the deadly incident but there was no reason to panic. He urged people to remain calm and vigilant.

Khan also said the official threat level remained at severe, meaning an attack is highly likely.

"One of the things that we can do is show that we aren't going to be cowed, is by voting on Thursday and making sure that we understand the importance of our democracy, our civil liberties and our human rights," Khan said.

"I'm not an advocate of postponing the election. I'm a passionate believer in democracy and making sure that we vote and we recognise actually that one of the things these terrorists hate is voting, they hate democracy," he said.
