The UK's last Guantanamo detainee, Shaker Aamer, has said in an interview with the Mail on Sunday that jihadis should "get the hell out" of Britain.
Aamer arrived back in the UK in October after being held captive in Guantanamo for 14 years.
He was first detained in Afghanistan in 2001 after being accused of having links to al-Qaeda, but the allegations were later dropped and he was cleared for release twice since 2007.
According to the campaign group Reprieve, "Shaker Aamer was taken, hooded and shackled, to the prison camp at Guantánamo Bay on the same day his youngest child was born – a child he had never met, touched, or even seen."
Aamer told the Mail on Sunday that his head was repeatedly slammed against a wall by officials in 2002: This morning on the BBC's Andrew Marr Show, The SNP's foreign affairs spokesman Alex Salmond said that former prime minister Tony Blair "must have known" about the alleged torture.
"The real politics of this is the allegation that in January 2002, British intelligence officers witnessed not just his abduction, which we knew about, but his torture," he said. "Also, as a point of detail, that they came into Bagram air base on the same flight as the then prime minister Tony Blair.
"The not unreasonable allegation that Shaker Aamer makes is that both the prime minister Tony Blair and the then home secretary Jack Straw must have known not just about his illegal abduction but also about his torture at the hands of the US authorities," said Salmond.
In his interview with the Mail on Sunday, Aamer spoke out against the 2013 murder of fusilier Lee Rigby: "How can you give yourself the right to be living here in this country, and living with the people and acting like you are a normal person, and then you just walk in the street and try to kill people?"
"Even if there is a war you cannot kill just anybody, you cannot kill kids, you cannot kill chaplains, you cannot just go in the street and get a knife and start stabbing people. If you are that angry about this country, you can get the hell out," he added.
Aamer also described the emotions he felt when he was reunited in the UK with his family, saying years of pain were "washed away" when he saw his wife.
When the news was announced that Aamer would be coming home, Labour leader Jeremy Corbyn offered his support, saying: "I attended an all-party delegation to Washington, in May of this year, which demanded his release. The pressure mounted by the British Parliament contributed to Shaker's freedom.
But we must recognise the crucial role played by the steadfastness of his family and the commitment of all those who campaigned for his release, whether they lobbied their MPs or demonstrated on the streets against this huge injustice."
Aamer told the Mail on Sunday that he had about 200 interrogators in the time he was held, and that other torture methods used against him included sleep deprivation and being shackled to the floor in sub-zero temperatures.
