Regarding Saadallah’s possible conversion to Christianity, see here. Christians have not been regarded as planning to travel to Syria for “extremist reasons.” The fact that MI5 suspected that Saadallah was going to do this adds weight to the possibility that his conversion to Christianity was a sham, or that he returned to Islam. Note the cousin who claims he converted to Christianity hasn’t seen him in three years.
“Reading terror attack suspect’s ‘brother’ claims he was defending himself during knife rampage and blasts the UK as ‘racist,’” by Luke May, Mailonline, June 22, 2020:
…Khairi Saadallah, who is thought to have only been released from prison for various offences 16 days ago, came to the attention of MI5 last year, after they suspected he was planning to travel to Syria for ‘extremist reasons’.
The 25-year-old allegedly claimed to have fought both for and against ISIS, though officials assessing him found he didn’t subscribe to any ideology or belief system and instead had mental health issues.
An investigation revealed no immediate risk or threat and he was not under surveillance at the time of his alleged rampage.
Saadallah was diagnosed with post-traumatic stress disorder and delusional and paranoid schizophrenia, requiring medication before his release, a source told the Sun.
He is thought to have come to the UK from Libya as a tourist in 2012 before claiming asylum as he was at risk from Islamic extremists in his homeland because he ‘liked to drink’ and didn’t lead a ‘strict religious life’.
However, once in the UK, he ended up in prison after committing several non-terror offences. He is even thought to have converted to Christianity and has a tattoo of a cross on his arm.
Saadallah boasted to friends in the UK that he had fought as a child soldier against the forces of former Libya leader Colonel Gaddafi – which he said had forced him to flee the country.
However, his cousin disputed these claims and said Saadallah had fled to avoid conflict.
She added that he heard voices and had psychotic episodes which left him thinking he was being followed.
The cousin, speaking to the Daily Telegraph, added that, three years ago, Saadallah started dating a British woman who was ‘very religious’ and he started going to church, eventually converting to Christianity.
Though the couple have since split, Saadallah maintained his faith, even have a tattoo of a cross etched onto his arm.
His cousin added: ‘ He’s not Muslim any more. It’s like he’s always been in the UK.’
His cousin in Libya said: ‘I can’t believe he’d do anything like this or be involved in anything to do with terrorism. He was at risk of extremists in Libya because he liked to drink and socialise and didn’t lead a strict religious life at all.
‘He started going to church and had tattoos all over his body including one of a cross on his arm. He did get in trouble in England and could be aggressive but I can’t ever imagine him getting drawn into something as serious as this.’
Among his other offences, in March 2019 Saadallah spat at Judge Sophie Toms at Reading magistrates court as she sentenced him for previous offences….
