We’ll soon be bringing our coverage of the shooting to a close, but before we do, let’s recap the key moments from today.

At 06:40 local time (12:40 BST), Dallas Police Department received a call requesting officer assistance after a shooting at an ICE facility.

The Department of Homeland Security says the gunman opened fire from an elevated position. Three people have died, including two ICE detainees and the attacker, who is said to have died from a self-inflicted gunshot wound. No ICE agents or law enforcement were hurt.

While the motive is still unclear, FBI Director Kash Patel said early stages of the investigation point to an "ideological motive" as he shared photos of bullets with "ANTI-ICE" written on them.

Patel said violence towards ICE facilities and officials "has to end", adding that the FBI and partners will lead investigative efforts.

At the moment, law enforcement is continuing its investigation, and the BBC will share updates with you in our news piece here.

Meanwhile, we are closing our live coverage.

The shooting happened at ICE's field office in Dallas, which covers north Texas and all of Oklahoma.

The office, just off a busy highway in north Dallas, is "not a detention facility", Tricia McLaughlin told Fox News.

According to CBS, the BBC's US partners, the facility is a temporary holding centre where detainees are kept before being transferred to a larger facility. "No detainee shall be confined in a hold room for more than 12 hours," according to an ICE detention standards manual., external

An ICE report from August says the Dallas facility also houses Enforcement and Removal Operations, the division responsible for arresting, detaining, and deporting foreign nationals.

Last month, a 36-year-old man was arrested outside the facility after he said he had a bomb in his backpack and showed officers what he said was a detonator on his wrist. The man was later arrested.

An assistant secretary in the Department of Homeland Security (DHS) has just shared previously unseen images, external from inside the Dallas ICE facility.

Bullet holes can be seen in an office window, and others have pierced a glass-encased American flag.

"Like everyone else, our ICE law enforcement officers just want to go home to their families at night. They are fathers and mothers. Sons, and daughters, brothers and sisters," writes Tricia McLaughlin.

Apart from the office, the DHS also says earlier that the gunman fired at an unmarked van near the facility.

Let's take a look at more reactions from politicians across the political spectrum.

"I ask you to pray for our law enforcement officers, particularly those charged with enforcing immigration laws and keeping the border secure. I also ask you to pray for any victims of this senseless, politically motivated shooting," Republican Senator Lindsay Graham says. "These must stop."

Republican Senator for Iowa Chuck Grassley says he is praying for those affected by the violence.

Texas Attorney General Ken Paxton says officials will keep doing "everything in our power to combat the alarming increase of targeted attacks against ICE and all law enforcement by evil, twisted individuals".

Gabrielle Giffords, a former Democratic Representative for Arizona, offers her support for the families of the victims, adding that "it’s clear our country is in the middle of a gun crime crisis".

She also criticises the Trump administration's "cruel and inhumane immigration policy".

• Just a reminder - while the FBI says there are "ANTI-ICE" engravings on bullets, officials have not yet confirmed the motive for the shooting

The Department of Homeland Security (DHS) has just given another update on casualties from the shooting in Dallas.

It says that, apart from the gunman who died from a self-inflicted gunshot wound, there were three other victims - two ICE detainees have been killed, while another is in a critical condition in hospital.

DHS adds that the gunman fired at an unmarked van near the facility, and at least one of the victims ran out of the vehicle and tried to get help from inside the ICE facility.

The gunman was positioned at an elevated location and opened fire from the rooftop of a lawyer’s office across the street from the ICE detention facility on Empress Street, DHS says.

Earlier, there was confusion over whether two or three people had died, including the attacker.

For some, today's shooting brings back memories of the killing of Charlie Kirk and the wider issue of political violence in America.

Earlier at a news conference, Dallas Mayor Eric Johnson said "it's a scary time", with a lot happening now across the US.

Republican Senator Ted Cruz has urged politicians to work together without demonising each other.

"We should not be putting language out there that inspires mad men to commit evil crimes," he said.

A short while ago, the Fort Worth Police Department - from the city next to Dallas - also responded to the shooting.

As well as urging locals to "say something" if they "see something", the department says:

"The violence that occurred in Dallas, Texas this morning is uncalled for and moments like this are deeply disturbing as it creates more division in our community at a time when the focus needs to be on how we can come together."

US Attorney General Pam Bondi says agents from the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives are helping out in Dallas.

You can also see officials from the bureau in the middle picture in the post below.

"Pray for the victims of this heinous act and for our brave law enforcement officers," Bondi writes on X.

At the news conference, officials said the shooting in Dallas this morning is still under active investigation.

As we've reported, officials in Dallas have just finished a news conference following Wednesday morning's shooting at an immigration facility in Texas. Here's what we know:

• Police confirmed that four people were shot, and two have died at the scene, including the attacker
• The FBI is investigating the attack as an act of targeted violence
• Police said evidence shows that rounds found near the attacker contained anti-ICE messages
• The victims were not named, but police said that no law enforcement officials were hurt in the shooting
• Officials appealed for political violence in America to stop. "It's a scary time," Dallas Mayor Eric Johnson said, while Texas Senator Ted Cruz urged politicians to tone down inflammatory rhetoric

Despite some information being given, many unknowns remain, including the identity of the victims and the gunman - police did not answer further questions, saying it is an active investigation.

We've just heard from local police in Dallas, who confirm that two people have died in the shooting at the ICE facility today, including the gunman.

This contradicts an earlier official statement from ICE that we reported on this page, which said two victims and the gunman were dead.

ICE has since removed the statement from its official X account.

FBI Director Kash Patel has just shared an image of the rounds mentioned in the news conference a short while ago.

"While the investigation is ongoing, an initial review of the evidence shows an ideological motive behind this attack," Patel writes on X.

He says one of the unspent bullets recovered has been engraved with the phrase "ANTI-ICE".

FBI agent Joe Rothrock ends the news conference after answering only a few questions from reporters.

He says this is an active investigation and he will not be answering any further questions.

Texas Senator Ted Cruz says "politically motivated violence" is wrong and "this needs to stop".

He refers to the assassination of conservative activist Charlie Kirk earlier this month.

Cruz says politicians need to work together without demonising each other, and that your political opponents are "not Nazis".

"We should not be putting language out there that inspires mad men to commit evil crimes," he adds.

Next up is Acting Director of the Dallas ICE Office Joshua Johnson, who says this is the second time he has had to address the media about a gunman at one of his facilities.

"I think that the takeaway from all of this is that the rhetoric have to stop," Johnson says.

"There are people out there seeing what is being placed online and then they are coming in and doing acts of violence against ICE employees.

"It has got to stop. It is dangerous and people are losing their lives."

Rothrock from the FBI says no members of law enforcement were hurt in the shooting.

He adds that officials won't be naming the victims yet, and appeals to the public for information.

"If any member of the public has information that would help the FBI's investigation, I would ask that you please report that," Rothrock says.

The FBI is investigating the incident as an act of targeted violence, FBI Special Agent Joe Rothrock says.

Early evidence shows that rounds found near the attacker contained messages that are anti-ICE in nature, Rothrock adds.

Dallas police chief Daniel Comeaux is now speaking.

He says that at about 06:40 local time, they received a call about the shooting.

They later learned that four people were shot - two were dead at the scene, including the attacker.

Local Dallas, Texas state and US federal authorities are now giving an update in a car park near where the shooting happened.

Mayor of Dallas Eric Johnson is up first and asks everyone to join him in "praying for the families of the folks who lost their lives".

He says there is a lot happening right now across the United States.

"It's a scary time," Johnson says, as he then praises law enforcement who ran to the scene.

"Lastly, I would ask all of you, all the city of Dallas residents who can hear me right now, let's be patient, let's be calm."
