The FBI identified a hostage taker killed at a Texas synagogue as a 44-year-old British citizen, after President Joe Biden earlier on Sunday said the gunman had used weapons he got off the street to commit "an act of terror."
The FBI identified the man as Malik Faisal Akram, who was killed after the safe release of his four hostages on Saturday night.
The incident in Colleyville, Texas, "was an act of terror,“ said Biden.
“Allegedly - I don't have all the facts, nor does the attorney general - but allegedly the assertion was he got the weapons on the street," Biden said.
"He purchased them when he landed and it turns out there apparently were no bombs that we know of. ... Apparently he spent the first night in a homeless shelter. I don't have all the details yet so I'm reluctant to go into much more detail,” the president said.
London’s Metropolitan Police said in a statement that its counter-terrorism police were liaising with US authorities about the incident.
FBI Special Agent in Charge Matt DeSarno said the hostage-taker was specifically focused on an issue not directly connected to the Jewish community, and there was no immediate indication that the man was part of any broader plan. But DeSarno said the agency’s investigation “will have global reach.”
An FBI Hostage Rescue Team on Saturday night stormed Congregation Beth Israel in Colleyville, about 16 miles (26 km) northeast of Fort Worth, ending a 10-hour standoff with police by the gunman, who disrupted a Sabbath service and took the rabbi and three other people hostage.
One hostage was released unharmed after being held for six hours and the remaining three were later safely freed by the FBI team.
Reporters at the scene late Saturday said they heard the sound of explosions, possibly flashbangs, and the sound of gunfire at the Reform Jewish synagogue in Colleyville.
SWAT teams from the Colleyville Police Department responded to the synagogue after emergency calls began at about 10:41 a.m. during the Sabbath service, which was being broadcast online.
FBI negotiators soon opened contact with the man, who said he wanted to speak to a woman held in a federal prison.
The man was heard having a one-sided phone conversation during a Facebook livestream of the service. The man could be heard ranting and talking about religion and his sister, repeatedly saying he did not want to see anyone hurt, the Fort Worth Star-Telegram reported.
The hostage-taker claimed to be the brother of Pakistani neuroscientist Aafia Siddiqui, who is serving an 86-year US prison sentence on her 2010 conviction for shooting at soldiers and FBI agents, and demanded that she be freed, a US official told ABC News.
Siddiqui is being held at a federal prison in the Fort Worth area. A lawyer representing Siddiqui, Marwa Elbially, told CNN in a statement that the man was not Siddiqui's brother and Siddiqui's family condemned his "heinous" actions.
