(CNN) The hostage situation at a synagogue in Colleyville, Texas, is over, according to the governor of Texas.
"Prayers answered. All hostages are out alive and safe," Gov. Greg Abbott tweeted about 20 minutes after a large bang and gunfire were heard in the direction of the synagogue.
The status of the suspect is not yet known.
The resolution came more than 10 hours after a suspect entered the Congregation Beth Israel as the synagogue was livestreaming its Sabbath morning service on Facebook. The livestream appeared to capture part of the incident before it was removed. Law enforcement officials told CNN they reviewed the stream and used it to gather clues on the incident and the individuals involved.
Two law enforcement officials told CNN that investigators believe the hostage taker may have been motivated by a desire to release Aafia Siddiqui, who is serving an 86-year sentence at a facility in Texas. She was convicted in 2010 on seven charges, including attempted murder and armed assault on US officers in Afghanistan.
A law enforcement official familiar with the investigation told CNN there were believed to be four hostages, including a rabbi, at the synagogue in Colleyville, just outside Fort Worth. Several hours into the standoff, Colleyville Police Sgt. Dara Nelson said one hostage had been released.
No injuries were reported at that time, Nelson said.
FBI negotiators were in contact with the suspect, Nelson said.
Officials said it's believed the suspect wanted Siddiqui released, based on both discussions with the suspect and audio heard on the synagogue's livestream.
The attorney who represents Siddiqui said Saturday "she has absolutely no involvement with" the taking of hostages at the synagogue and said the perpetrator is not Siddiqui's brother.
"She does not want any violence perpetrated against any human being, especially in her name," Marwa Elbially told CNN by phone. "It obviously has nothing to do with Dr. Siddiqui or her family."
"Whoever the assailant is, we want him to know that his actions are condemned by Dr. Aafia and her family," Elbially said. "We implore you to immediately release the hostages and turn yourself in."
At the request of the hostage taker, the rabbi of the congregation who was being held hostage called a well known rabbi in New York City, according to two officials briefed on investigation.
The FBI interviewed the New York City-based rabbi who spoke to the hostage taker earlier Saturday. The hostage taker, who has no connection with the rabbi, told her that Siddiqi was framed and he wants her released, the officials said.
Congregation member Stacey Silverman described watching the livestream for more than an hour, listening to the suspect ranting, sometimes switching between saying "I'm not a criminal" to being apologetic about the situation. The suspect was vacillating between different languages and "screaming hysterically," she said.
"At any moment, I thought there was going to be a gunshot," Silverman said, adding that the suspect claimed to have a bomb.
Congregation Beth Israel is affiliated with the Union for Reform Judaism, whose website indicates the congregation serves 157 membership families.
The synagogue, established in 1999 with 25 membership families, was the first Jewish congregation in Northeast Tarrant County, according to CBI's website. The CBI community officially opened its doors to its own new building in 2005.
CBI holds Sabbath morning services every Saturday, and members and non-members alike are welcome to watch along from home on the livestream, a practice many synagogues have adopted in the wake of the pandemic.
In 2010, Siddiqui was sentenced to 86 years in prison by a New York federal judge following a 14-day trial. A jury found her guilty of the attempted murder of US nationals and government employees, as well as assault against US officers and employees.
Siddiqui -- a Pakistani scientist who graduated from the Massachusetts Institute of Technology and obtained a doctorate from Brandeis University -- was taken into custody for questioning by the Afghan National Police in 2008, who said they found handwritten notes referring to potential targets of a "mass casualty attack," according to a federal indictment.
When a group of Americans attempted to speak to her, prosecutors said she was able to grab a US soldier's rifle and open fire on the interrogation team, although no one was hit by the gunfire.
At sentencing, the judge found that a terrorism enhancement applied to her crimes, citing statements she had made that the judge concluded demonstrated her actions and intent to retaliate against the US government, including "I hate Americans" and "Death to America."
Siddiqui's defense argued she was incompetent to stand trial. But Siddiqui clashed repeatedly with her lawyers, telling the judge at sentencing, "If anybody thinks that it is my paranoia or whatever, I'm not paranoid. I'm not mentally sick. I do not agree with that." She also stated her belief that Israel "masterminded 9/11."
Her conviction has been the subject of regular protests in the US and overseas. Frequent demonstrations have been organized by the Aafia Foundation, a group named for her. That group has claimed that she was assaulted in prison last year.
Her family has said in interviews with CNN that she is not a terrorist.
During a deadly hostage crisis in Algeria in 2013, a spokesperson for a militant group offered to release hostages if Siddiqui was released from US prison, along with Sheikh Omar Abdel Rahman, the mastermind of the 1993 World Trade Center attack, who has since died in prison.
Siddiqui is being held in a medical facility that's part of a federal prison in Fort Worth, with a release date set for 60 years from now.
