LONDON (AP) — A British man who held four people hostage in a Texas synagogue ranted against Jews and American wars in countries such as Afghanistan as his brother pleaded with him to give up and free the captives, a recording of the conversation shows.

In the expletive-filled recording posted on the website of The Jewish Chronicle, 44-year-old Malik Faisal Akram said he was “bombed up” and equipped with “every ammunition” as he talked to his brother Saturday from inside Congregation Beth Israel in the Dallas suburb of Colleyville.

Gulbar Akram urged his brother to lay down his weapons and return to his children alive.

“You don’t need to do this. Why are you doing this?” he said. “Just pack it in. You’ll do a bit of time, and then you’ll get out.”

“These guys you’ve got there, they’re innocent people, man,” he said.

In response, Akram became increasingly agitated and said he hoped U.S. authorities would take notice of the Jewish hostages and agree to his demand that they release Aafia Siddiqui, a Pakistani neuroscientist convicted of trying to kill U.S. soldiers in Afghanistan.

Akram said he had prayed about the attack for two years. He said he was ready to become a martyr and that his children shouldn’t cry at his funeral.

“I promised my brother when I watched him on his deathbed that I’d go down as a martyr,” he said at one point. One of his younger brothers, who contracted COVID-19, died a few months ago.

“I’ve come to die, G, OK?″ the hostage-taker told his brother. “I’ve prayed to Allah for two years for this … I’m coming back in a body bag.”

Saturday’s 10-hour standoff at the synagogue ended after the last hostage ran out of the synagogue and an FBI SWAT team rushed in. Akram was killed, though authorities have declined to say who shot him.

In a webinar Thursday hosted by the Anti-Defamation League, FBI Director Christopher Wray said the agency understands that such acts are terrifying to the entire Jewish community.

“This was not some random occurrence. It was intentional. It was symbolic, and we’re not going to tolerate antisemitism in this country,” Wray said.

The FBI continues to search phones and other devices as it investigates why Akram targeted this particular synagogue, Wray said.

The Chronicle said the recording was part of a longer 11 1/2-minute recording that it obtained from a “security source.” The Associated Press was not able to independently confirm the authenticity of the recording, but experts believe it to be genuine.

Meanwhile, British police said Thursday that they have arrested two people in connection with the hostage-taking.

Counter Terrorism Police North West said one man was arrested Thursday in Birmingham and another in Manchester. They were being held for questioning and have not been charged.

The police did not disclose details about the two people. British police do not release names and details of detainees until they are charged.

On Sunday, police arrested two British teenagers in Manchester as part of the investigation. The teens were Akram’s sons, two U.S. law enforcement officials told AP. They were later released without charge.

Malik Faisal Akram was from Blackburn, an industrial city in northwest England. His family said he had been “suffering from mental health issues.”

He entered the United States on a tourist visa about two weeks earlier and spent time in Dallas-area homeless shelters before the synagogue attack.

The FBI has called the incident “a terrorism-related matter” targeting the Jewish community.

British media, including the Guardian and the BBC, have reported that Akram was investigated by the domestic intelligence service MI5 as a possible “terrorist threat” in 2020. But authorities concluded that he posed no danger, and the investigation was closed.

The White House said Tuesday that Akram had been checked against U.S. law enforcement databases before entering the country but raised no red flags.
