Former US National Security Adviser, HR McMaster, has condemned the US withdrawal from Afghanistan and said today's attack was "only the beginning".
Gen McMaster, who served as a senior US officer in Afghanistan, told BBC News the US had prioritised "getting the hell out of there, regardless of what the consequences will be" and that the attack at Kabul airport was "what happens when you surrender to a terrorist organisation".
“Maybe this moment is the time that we can stop our self delusion that these groups are separate from one and other and recognise that they are utterly intertwined and interconnected, and what we are seeing is the establishment of a terrorist, jihadist state in Afghanistan. And all of us will be at much greater risk as a result."
He said his former boss, President Donald Trump, had been "played" by the Taliban in negotiations last year. Mr Trump agreed to remove US troops from Afghanistan within 14 months.
