The fall of Afghanistan to the Taliban is likely to have “emboldened” UK terrorists, the director general of MI5 has warned.
Ken McCallum told the BBC that while the terror threat would not change overnight, there could be a “morale boost” for extremists.
The UK has to be “vigilant” for a rise in “inspired terrorism”, he said.
A total of 31 late-stage attack plots have been foiled in the UK in the past four years, said Mr McCallum.
That includes six during the pandemic period alone, he added. While they were largely Islamic extremist plots, there were also a “growing number” of attacks planned by extreme right-wing terrorists.
“The terrorist threat to the UK, I am sorry to say, is a real and enduring thing,” he added.
Mr McCallum, speaking to BBC Radio 4’s Today programme on the eve of the 20th anniversary of the 9/11 attacks on the US, said that smaller-scale, “inspired” terrorist acts by those already in the UK made up the largest number of threats faced by MI5.
“There is no doubt that events in Afghanistan will have heartened and emboldened some of those extremists and so being vigilant to precisely those kinds of risks is what my organisation is focused on along with a range of other threats,” he said.
While the government says it will judge the Taliban by their actions, the UK security service would plan for the possibility “more risk, progressively, may flow our way”, Mr McCallum said.
“Terrorist threats tend not to change overnight in the sense of directed plotting or training camps or infrastructure – the sorts of things that al-Qaeda enjoyed in Afghanistan at the time of 9/11,” he said.
“These things do inherently take time to build, and the 20-year effort to reduce the terrorist threat from Afghanistan has been largely successful.
“But what does happen overnight, even though those directed plots and centrally organised bits of terrorism take a bit longer to rebuild… overnight, you can have a psychological boost, a morale boost to extremists already here, or in other countries.”
Former chief of the UK defence staff General Lord Richards said we are closer to “another 9/11” following the US and UK’s withdrawal from Afghanistan.
“I fear the Taliban and some extremist jihadist groups are, whatever they like to say, in each other’s pockets,” he told LBC. “Scores will be settled, debts will have to be repaid and there will be ungoverned space opened up in Afghanistan which those groups will exploit and the ability of the Taliban to actually manage them will be minimal.”
