Malik Faisal Akram, 44, was shot dead by an FBI SWAT team 10 hours into the stand-off, and all four hostages were released unharmed.

In the expletive-laden phone call, released by the Jewish Chronicle, he made a number of threats and antisemitic remarks and claimed to have "promised" his younger brother "on his deathbed" he would "go down a martyr".

One of his younger brothers reportedly died three months ago from COVID.

His other brother, Gulbar Akram spoke to him from a police station in Blackburn and attempted to persuade him to surrender, but Malik Akram told him: "Don't cry at my funeral. Because guess what, I've come to die G, ok?"

Gulbar later told Sky News Akram was on the phone with his two teenage children when he was killed.

Akram ranted about American conflicts overseas and said: "I'm setting a precedent."

His actions, he said, would "[open] the doors for every youngster in England to enter America and f*** with them".

When Gulbar urged himself to end the siege and hand himself in to the police, Akram said he had been "praying to Allah for two years for this".

"I'd rather live one day as a lion than 100 years as a jackal," he added.

"I'm going to go toe-to-toe with [police] and they can shoot me dead... I'm coming home in a body bag."

He repeatedly asked for the release of Aafia Siddiqui, a Pakistani neuroscientist imprisoned for having ties to Al Qaeda.

But when Gulbar told him they would not release Siddiqui, he replied: "Who gives a f***, listen to me. Allah is with me.

"I'm not worried in the slightest, I don't even flinch, man."

Akram's family has said he was "suffering from mental health issues".

"There was nothing we could have said to him or done that would have convinced him to surrender," his brother Gulbar said in a statement.
