Homeland Security chief: Jihadists are plotting ‘another 9/11’ using planes

Daily Mail Online, October 18, 2017.

Islamic State fanatics and other terror groups are planning another massive attack on the scale of 9/11, a top US security chief warned today.

Elaine Duke, Donald Trump’s acting Secretary of Homeland Security, said jihadists were using crude knife and van attacks to keep their members engaged and their finances flowing as they plot another ‘big explosion’ similar to the September 2001 atrocities.

Speaking at the US embassy in London, she said intelligence is pointing to extremists plotting to take down planes to inflict mass civilian casualties.

Mrs Duke said ISIS is currently in an ‘interim’ period focusing on a much bigger endgame.

The security chief, who has served three US presidents, said: ‘The terrorist organisations, be it ISIS or others, want to have the big explosion like they did on 9/11. They want to take down aircraft, the intelligence is clear on that.

‘However, in the interim they need to keep their finances flowing and they need to keep their visibility high and they need to keep their members engaged, so they are using small plots and they are happy to have small plots.’

She added: ‘Creating terror is their goal and so a van attack, a bladed weapon attack, causes terror and continues to disrupt the world – but does not mean they’ve given up on a major aviation plot.’

Yesterday Mrs Duke said the prospect of a terrorist blowing up an airline using a laptop was just one of the threats facing airlines worldwide.

She said the free movement of goods and people means security has to be tightened in individual countries around the world.

She said: ‘The laptop is one of the many aviation threats, we will never be comfortable and we will always be evolving.

‘What we believe is that because of the movement of goods and people, we have to raise the baseline worldwide, we can’t only consider our borders.’ Mrs Duke went on: ‘We think the level of terrorist threat against the United States too is extremely high.

‘I think that it is challenging for you because you have the proximities to other countries, the ease of movement from some of the terrorist safe havens is a little easier for you, but we feel the terrorist threat is very high in the United States.’

Asked how the US is tackling the threat of another 9/11-style atrocity, she said: ‘We have worked on some strong measures that we can’t talk about. We are trying to play the away game and that is working against them in their terrorist safe havens and homes.

‘We do have some terrorist groups on the move, you just saw the take-over of Raqqa and so if we can keep them declining and moving they have less time to sit and prepare.’

Mrs Duke warned that the number of home-grown violent extremists, mostly inspired by terrorist organisations, is increasing in the US. She said the ability of IS militants to put terrorist propaganda on the internet will appeal more and more to extremists as they are pushed out of Syria and Iraq.

Mrs Duke said web giants need to do more to detect extremist content online, and one way of doing this could be using the same technology used to identify people in passenger lists….
