Earlier today, the Foreign Secretary claimed the UK had not pushed to keep the gate open before a suicide bomber detonated explosives. However, according to reports, the decision to keep the gate open had been a joint UK/US decision. Previously, the US had claimed UK officials had asked to keep the gate open in order to facilitate the movement of personnel towards the airport.

       The Guardian's Dan Sabbagh said: "Decision to keep Kabul's Abbey Gate open last week after terror warnings was a joint US/UK decision say British sources."

       A seperate report claimed US forces had intended to close the gate on Thursday before R Adm Peter Vasely, the commander of the US forces in Afghanistan claimed it would remain open to accelerate the UK withdrawal.

       This morning, Mr Raab said the Politico report was untrue during an interview with Sky News.

       He said: "We got our civilian stuff out of the processing centre by Abbey Gate, but it's just not true to suggest that, other than securing our civilian staff inside the airport, that we were pushing to leave the gate open."

       The Foreign Secretary has come under criticism for a chaotic evacuation leaving the Taliban now have control of the country.

       It is unclear how many Afghans the UK has failed to evacuate which has led to some such as Piers Morgan to call for his resignation.

       In a furious tweet, Piers said: "Dominic Raab is such a lying slippery toad.

       "I’d have just one question for him today: you’ve been an abject failure in this crisis, and went shamefully missing in action - why haven’t you resigned?"

       This comes as Mr Raab refused to rule out exercising the right "self-defence" against ISIS.

       Speaking on Tuesday morning, Mr Raab refused to be drawn on the details of any potential strike but revealed the UK would be willing to do so.

       He told Sky News: "Well, I am not going to comment anymore on the operational details that the admiral referred to.

       "But of course, in extremis, the UK retains the right to exercise self-defence and that must include in relation to terrorist groups operating from abroad."

       The Foreign Secretary also hit back at claims the UK's 20-year operation had been a failure.

       He insisted the number of UK nationals left behind in the state is in the low hundreds.

       Mr Raab said on Tuesday he was unable to give a "definitive" figure on how many Afghans the UK had failed to airlift to safety after the Taliban seized power.

       Commenting further on the strikes, Mr Raab said: "We have still got that record of 20 years of no terrorist attacks from within Afghanistan, we now need to see the Taliban live up to what it said about no safe haven for terrorist groups.

       "There are standard operating procedures of dealing with an emerging crisis like that.

       "Of course, the House of Commons debates potential military interventions all the time."

       Air Chief Marshal Sir Mike Wigston, the Chief of the Air Staff suggested the UK must be willing to strike back against the terrorist group.

       Despite leaving the country, Sir Mike said the UK would be willing to hit back against the terrorist group if it grows in influence in Afghanistan.

       Although the country is hard to access, he also claimed the UK is one of the few countries which can.

       In an interview with The Daily Telegraph, he said: "Ultimately what this boils down to is that we've got to be able to play a global role in the global coalition to defeat Daesh, whether it's strike, or whether it's moving troops or equipment into a particular country, at scale and at speed.

       "If there's an opportunity for us to contribute I am in no doubt that we will be ready to - that will be anywhere where violent extremism raises its head, and is a direct or indirect threat to the UK and our allies.

       "Afghanistan is probably one of the most inaccessible parts of the world, and we're able to operate there."

       While Western forces withdrew from the state, Islamic State Khorasan Province, claimed responsibility for two attacks.

       A suicide detonated explosives last week which killed 169 Afghans and 13 US soldiers.
