Soliman had at least 14 unused Molotov cocktails with him at the time of his arrest, according to documents filed for the federal criminal case against him.

It includes details police had earlier reported, that he threw two lit Molotov cocktails at individuals participating in the gathering, yelling “Free Palestine!” as he did so, causing burn injuries to eight individuals.

The government alleges that in addition to the 14 unlit Molotov cocktails, police also found a backpack weed sprayer, found to contain octane gasoline.

In his car, the document says police found red material consistent with the rags hanging out of the remaining incendiary devices, a red gas container and paperwork with the words, “Israel,” “Palestine,” and “USAID".

Mohamed Sabry Soliman has been charged with a hate crime offence, the FBI affidavit says.

"I seek a criminal complaint charging Mohammed Sabry SOLIMAN (“SOLIMAN”) with one count of a hate crime offense involving the actual or perceived race, religion, or national origin," FBI Special Agent Jessica Krueger said in a court filing seen by the BBC.

The charge follows a police interview with Soliman after he was arrested.

We're continuing to sift through this FBI affidavit and will bring you more details shortly.

We're now looking at details released by the FBI, which says that the alleged attacker had been planning Sunday's attack for a year.

He had been waiting until after his daughter graduates, an affidavit from special agent Jessica Krueger states.

It sets out that he arrived at the scene of the crime at 12:55 local time and waited for the Run for Their Lives group.

The FBI says that after his arrest, Mohamed Soliman told police that Zionists were his targets and that he would conduct the attack again.

For context: In the document, the FBI defines “Zionist” to mean "individuals who believe in the establishment of a Jewish state and are supportive of the government of Israel".

Sunday night marked the beginning of the Jewish holiday of Shavuot, a two day holiday that commemorates the story of the Jews receiving the Ten Commandments and the Torah on Mount Sinai. It was also historically a harvest festival.

Jewish people typically celebrate the holiday with synagogue services. Some have a custom to study the Old Testament late into the night, and many synagogues and Jewish cultural institutions hold events for the community. Many Jews will also eat foods containing dairy specifically for the holiday.

For Boulder, however, the attack came just hours before Shavuot was set to begin, casting a pall over what has historically been one of the more joyful holidays on the Jewish calendar.

US prosecutors say they will give an update in Boulder to give an update on investigations about yesterday's attack at 14:30 local time (20:30 GMT).

That's an hour after the suspect will have been due in court.

We will bring you the latest from that briefing when it gets underway.

While details about Sunday’s attack in in Boulder, Colorado, are still emerging, that hasn’t stopped the incident from quickly being pulled into the vortex of American politics.

The US president, along with members of his administration, have been quick to draw conclusions about the attack, which touches on two of the hottest partisan issues – the Gaza war and immigration.

US Ambassador to Israel Mike Huckabee said that the American media’s coverage of the war in Gaza was “contributing to the antisemitic climate” conducive to Sunday’s violence.

White House Deputy Chief of Staff Stephen Miller – one of the administration’s fiercest advocates for aggressive immigration enforcement - wrote on X that the suspect in Colorado, Mohamad Sabry Soliman, had been granted a work permit by the Biden administration in 2023 after he overstayed his tourism visa.

“Suicidal migration must be fully reversed,” he concluded.

This is almost certainly just a taste of the rhetoric to come – whether it is used to defend current Trump administration policies on Israel and immigration or becomes the basis for new proposals in the days ahead.

In his first comments since yesterday's attack, US President Donald Trump says the suspect in the attack would be "prosecuted to the fullest extent of the law".

He joins others in his administration by blaming his predecessor, Joe Biden, for Mohamed Soliman being in the country, and points to the attack as evidence to support his border policies.

US officials have told the BBC that Soliman arrived in the US on a tourist visa in August 2022 that expired in February 2023. He then filed for asylum in the US.

Trump adds: "My heart goes out to the victims of this terrible tragedy and the Great People of Boulder, Colorado!"

Run for Their Lives, the organisation that holds weekly running and walking events to call for the release of hostages being held by Hamas in Gaza, says it is committed to its goal despite the violent attack on its event on Sunday.

The group began the regular events on 15 October 2023 in response to the Hamas attack on Israel on 7 October, in which about 1,200 people were killed and 251 others were taken hostage.

In a statement, the organisation said: "These walks have been held every week since then for all the hostages - without any violent incidents until today."

At least 54,418 people have been killed in Gaza since Israel launched its military campaign in response to the 7 October attack, according to the territory's Hamas-run health ministry. Some hostages held by Hamas have been released, as have the bodies of some who died in captivity. At least 20 of the remaining 58 hostages are believed to still be alive inside war-torn Gaza.

The organisation says it "remains committed to our mission until ALL the hostages are returned back home!"

More details are emerging about the alleged attacker Mohamed Soliman.

Sources told the BBC's US partner CBS News that from the beginning of 2024, Soliman worked for a company called Veros Health in Centennial, Colorado - about a 45 minute drive from Boulder. He worked there for "less than six months", they said.

Veros Health is an independent physicians practice, and it uses a professional onboarding program that would have vetted the legal status of new hires.

The White House has claimed Soliman overstayed his visa and is in the country illegally.

We are learning more about how yesterday's events unfolded from eyewitnesses.

Alex Osante, who was eating at an Italian restaurant at the time, said he was alerted to the incident when he heard a loud bang followed by the sounds of people screaming.

Police say the suspect threw Molotov cocktails - a bottle filled with flammable liquid that is lit before being thrown, at the crowd. Osante said the suspect threw a second bottle but this time "he himself caught on fire", which caused him to take off his shirt.

Social media videos of the incident shows the suspect shirtless. A mugshot, released by police today, also shows him with facial injuries and a big white bandage on his right ear.

The Department for Homeland Security (DHS) has confirmed to the BBC that the suspect, Mohamed Soliman, had filed for asylum in the US in September 2022.

The senior DHS official says that Soliman had entered the US in August 2022 on a B2 visa that expired on February 2023.

US politicians from the local to national level have spoken out about Sunday's attack.

Senate Minority Leader Chuck Schumer called the attack a "vile, antisemitic act of terror" in a post on X, external and said he's closely monitoring the situation with the FBI.

"When antisemitism is allowed to fester, when it spreads unchecked, and when too many look the other way, history has shown us where it leads: to hatred, to violence, to terror," he wrote.

FBI director Kash Patel also posted to X, external, calling the incident a "targeted terror attack".

Colorado Governor Jared Polis released a statement condemning the attack in his state and saying his thoughts are with the injured.

"As the Jewish community reels from the recent antisemitic murders in Washington DC, it is unfathomable that the community is facing another antisemitic attack here in Boulder on the eve of the holiday of Shavuot," he wrote.

President Donald Trump hasn't spoken about the attack, but Stephen Miller, the White House's deputy chief of staff for policy, posted on X that Soliman was an undocumented immigrant.

Boulder police has just posted an update on social media, in which it clarifies that no victims have died as a result of Sunday's attack.

It says the update comes as a result of questions to the police force - there had been uncertainty over whether anyone had died after Boulder county court records showed the suspect booked on several charges including first degree murder.

Along with a mugshot of Soliman that appears to show him with injuries to his face and ear, Boulder police says it will hold a news conference later today with further details.

The suspect arrested over the attack had overstayed his visa, according to Stephen Miller, Donald Trump's deputy chief of staff for policy.

In 2022, Soliman arrived in California on a non-immigrant visa that expired in February 2023, multiple sources told CBS News, the BBC's partner in the US. He had recently been living in Colorado Springs.

Trump's deputy chief of staff for policy, Stephen Miller, said on X that, external Soliman was given a work permit by the Biden administration after he had overstayed his visa. This has not been verified by the BBC.

Looking at the Boulder county court records, the suspect arrested over the attack is due to appear in court at 13:30 local time (19:30 GMT).

County jail records show that Mohamed Sabry Soliman was booked on several charges including first-degree murder, however we are yet to hear from officials that any victims have succumbed to their injuries. We have contacted Boulder county sheriffs and Boulder city police to find out more.
