Benjamin Crump, the lead attorney for the family of George Floyd, says he was "tortured to death" by police, who kneeled on him until he died.

An official autopsy has ruled Floyd's cause of death homicide.

Floyd's family is visiting the site where he died in Minneapolis last week. They are expected to speak soon.

One officer involved in Floyd's arrest has been arrested and charged with murder, but three other officers at the scene have not been arrested.

"We expect all of the police officers to be arrested before we have the memorial tomorrow," says Crump, with Floyd's son standing by his side.

Videos of piles of bricks near the sites of protests in different cities have been viewed by millions.

Those sharing these videos broadly make two different claims: some say the bricks were carefully deposited by Antifa activists to be thrown at police, and others say they were planted by officers so that protesters can be portrayed as violent.

We’ve investigated a number of the most popular videos and so far, there doesn’t seem to be any evidence to suggest nefarious activity is at play.

In one case in Fayetteville, North Carolina, the bricks were placed on a street last week for pavement restoration work that was meant to be carried out this week.

In another case in Boston, local police said two officers were collecting damaged bricks that posed a risk to pedestrians.

The BBC’s anti-disinformation unit has investigated various misleading videos and narratives about the protests.

A statement from South Africa's government urges US security forces to use “maximum restraint” in responding to protests over the police killings of African-Americans.

“South Africa, too, supports the clarion calls for practical action to address the inadequacies highlighted by protesters,” the statement adds, noting that Americans had also supported the fight to end apartheid.

But violence, the statement warns, “seriously detracts from drawing international awareness to the legitimate concerns about violence against defenceless black people and other minorities in America.”

The National Guard will investigate an incident near the White House on Monday where one of its helicopters hovered close to non-violent protesters. Experts say this manoeuvre is typically used to intimidate and disperse crowds with the wind generated from the chopper's rotors.

Maj Gen William J Walker, who commands the Washington DC National Guard, has directed an investigation into the “low-flying manoeuvre,” according to a spokesman.

Social media showed at least two helicopters making the manoeuvre - and one had a red cross on it, showing that it was a medical helicopter.

“This was a foolish move,” Geoffrey Corn, a former Army lawyer and professor at the South Texas College of Law, told the Washington Post, external.

“The symbolic significance of the Red Cross is pervasive: It denotes a ‘noncombatant’ function of the armed forces.”

The wind broke branches of trees with some landing near protesters, and sent rubble and broken glass flying through the streets. At least one helicopter descended below the height of nearby buildings.

Defence Secretary Mark Esper said earlier today that he has also ordered the Army to conduct an inquiry into the incident.

Minnesota governor Tim Walz has apologised directly to CNN reporter Omar Jimenez after he was arrested on Friday.

Jimenez was led away in handcuffs while he was live on air early on Friday while covering protests in Minneapolis. His cameraman and producer were also detained, apparently because they did not move on when told.

Walz apologised to CNN President Jeff Zucker shortly after the incident but today took the chance to say sorry to Jimenez face-to-face.

“Thank you for the professionalism, thank you for understanding and I’m deeply sorry," Walz told the correspondent in an interview.

"And you know that we’ve made other mistakes on this as far as making sure that you have access, but protocols and everything else we're learning have to change, because we have to create the space for you to tell the story.”

Here is the moment the CNN crew were detained.

One of Trump's most controversial moves during this protest has been his photo-op posing with a Bible outside a landmark church in Washington.

Among those with him was Defence Secretary Mark Esper.

He is now saying he was given no advance notice that White House officials would walk through a recently-cleared protest to pose for pictures outside the church.

"I was not aware that a photo op was happening," he said in an interview.

"I thought I was going to do two things: to see some damage and to talk to the troops," he told NBC, adding that he thought they were going to see a public restroom that was damaged the night before.

"I didn't know where I was going," Esper said. "I wanted to see how much damage actually happened." He added that he had "no idea" that police would disperse the crowd.

The church photo-op led one former top policy official at the Pentagon to quit, writing a scathing resignation letter.

"President Trump’s actions Monday night violated his oath to 'take care that the laws be faithfully executed,' as well as the First Amendment 'right of the people peaceably to assemble,'" wrote former Under Secretary of Defense for Policy James Miller.

"You may not have been able to stop President Trump from directing this appalling use of force, but you could have chosen to oppose it. Instead, you visibly supported it.”

Trump has received a fair amount of flak for his resort to the White House bunker as protests heated up nearby last week.

Now, in a wide-ranging Fox News radio interview, he says he entered the secure bunker on Friday "all for inspection". He also said he went to the bunker in the daytime, and before protests began to rage.

"I wasn't down. I went down during the day and I was there for a tiny short period of time," he says, adding that he visited it two or three times. Protesters have recently adopted the nickname Bunker Baby.

He also claimed to have received a positive response from religious leaders to his photo-op at a church opposite the White House, despite the visit being condemned by the Washington DC archdiocese and the episcopal leader that oversees that church.

Trump's church visit shocks religious leaders

He also suggested that he did not know protesters would be cleared to make a path for his visit, despite explosions being heard from the White House Rose Garden, where he delivered a speech to the nation before walking through Lafayette Square to the St Johns Church.

"When I went, I didn't say 'Oh, move them out.' I didn't know who was there. I figured I was going walk over the church, very nearby," he continued.

US Defence Secretary Mark Esper has said he does not support deploying the army to end protests over the death of George Floyd and racial injustice.

It comes two days after President Donald Trump threatened to use the military to quell the demonstrations.

"I do not support invoking the Insurrection Act," Esper said, speaking at the Pentagon.

“The option to use active duty forces in a law enforcement role should only be used as a matter of last resort, and only in the most urgent and dire of situations. We are not in one of those situations now," he said.

He went on to call the killing of George Floyd "a horrible crime".

"The officers on the scene that day should be held accountable for his murder. It is a tragedy that we have seen repeat itself too many times," Esper said.

The Associated Press has said two of its journalists were "shoved" and sworn at by police in New York dispersing protesters after the start of curfew on Tuesday night.

Despite carrying press credentials and identifying themselves as journalists, officers "surrounded, shoved and yelled expletives" at the two men, who captured the incident on video, AP said on Wednesday, external.

Law enforcement officials said they would "review" the incident “as soon as possible.”

Dozens of media workers covering the unrest in the US have reported being targeted by security forces using tear gas, rubber bullets and pepper spray.

The death of an unarmed African-American while in police custody shows the US' "true face", Iran's supreme leader Ayatollah Ali Khamenei has said.

"That a policeman calmly puts a knee on the neck of a black person and keeps it there... while several other policemen stand there watching and taking no action, is not something that has just emerged," Khamenei said in a speech on Wednesday.

"This is America's nature, this is what America has been doing to the whole world all along," he said.

Already strained tensions between the US and Iran deteriorated further earlier this year after the US killing of a top Iranian general in an airstrike in January.

Last year, Iran had its own mass protests against a rise in fuel prices. According to Amnesty International, more than 300 people were killed in a crackdown against the unrest, while thousands of others were reportedly arbitrarily detained.

Mostly, it would seem that Floyd was simply trying to live life as any other American, in search of betterment in the face of both personal and societal challenges.

The death of George Floyd is far from the first killing of a black American to cause widespread expressions of outrage.

Look at our timeline here.

Donald Trump has said again that he has done more for the US black community than any president with "the possible exception of another Republican President, the late, great, Abraham Lincoln".

Mr Trump took a swipe at Joe Biden, saying he had done more for the black population than his presidential rival had "in 43 years".

Joe Biden has criticised Mr Trump for using the crisis to appeal to his supporters, saying he was "serving the passions of his base".

Mr Trump also took aim at the "killers, terrorists, arsonists, anarchists, thugs, hoodlums, looters, ANTIFA & others" who he believes are behind violent protests.

The city of Ferguson, Missouri - where an unarmed black teen was killed by a white policeman in 2014, sparking nationwide protests - has elected its first black mayor.

Ella Jones also becomes the first woman to serve in the position after the vote on Tuesday night, according to US media.

America's Drug Enforcement Agency (DEA) has reportedly been given the all-clear to conduct "covert surveillance" on protesters taking to the streets over the death of George Floyd.

Buzzfeed News reports that the Department of Justice has allowed the surveillance powers on a temporary basis.

DEA agents will also be able to gather intelligence on protesters and disseminate information with local and state law enforcement, a memo says.

"Police agencies in certain areas of the country have struggled to maintain and/or restore order,” the memo reportedly said in making the case.

A police offficer in Denver, Colorado, has been sacked after posting a photo on social media of himself and two other officers in riot gear with the caption "Let's start a riot".

Denver police began an inquiry after the posting by Thomas McClay on Sunday on Instagram.

“The Internal Affairs investigation revealed that the officer violated the department’s social media policy, posted content inconsistent with the values of the department, and the officer has been terminated," a statement read.

City officials told CBS News in Denver, external that Officer McClay had been a probationary employee.

UK Prime Minister Boris Johnson has said he "completely understand[s]" public anger in the US and abroad over the death of African-American George Floyd in police custody last week.

Questioned in parliament about the lack of a UK government response, Johnson responded: "Of course black lives matter and I totally understand the anger, the grief that is felt, not just in America but around the world and in our country as well...

"The only point I would make to the House is that protests should be carried out lawfully and in this country, protests should be carried out in accordance with our rules on social distancing."

Thousands of people took part in protests in London on Sunday. Another demonstration is planned for London's Hyde Park at 1pm on Wednesday as part of a day of action against discrimination.

Pope Francis has spoken out against the killing of George Floyd.

"Dear brothers and sisters in the United States, I have witnessed with great concern the disturbing social unrest in your nation in these past days, following the tragic death of Mr. George Floyd," the Pope said from the Vatican.

He added that he was praying for “repose of the soul of George Floyd and of all those others who have lost their lives as a result of the sin of racism”.

"My friends, we cannot tolerate or turn a blind eye to racism and exclusion in any form and yet claim to defend the sacredness of every human life," he added.

"At the same time, we have to recognise that the violence of recent nights is self-destructive and self-defeating. Nothing is gained by violence and so much is lost."
