Tens of thousands of people have demonstrated, mainly peacefully, across the United States for an eighth night following the death of African-American George Floyd in police custody.
One of the biggest protests, joined by Floyd's relatives, took place in his hometown of Houston, Texas.
Many defied curfews in several cities, imposed after violence and looting in some districts on Monday night.
The Pope has issued a call for racism not to be ignored.
"We cannot tolerate or turn a blind eye to racism," he said. But he also condemned the violence: "Nothing is gained by violence and so much is lost."
The Floyd case has reignited deep-seated anger over police killings of black Americans and racism.
Demonstrators have taken to the streets – not only to express their outrage at the treatment of Mr Floyd – but to condemn police brutality against black Americans more widely.
George Floyd death
In central Washington DC police fired tear gas after darkness. The military were again on the streets of the capital and helicopters hovered above protesters marching towards the White House.
Traffic was blocked in New York's Manhattan district as protesters ignored a night-time curfew, which had been extended for a week. Video footage showed them surrounding a police van.
In Houston, where Floyd is due to be buried, Mayor Sylvester Turner, told the crowds people should know that he "did not die in vain".
Big rallies were also held in Los Angeles, Philadelphia, Atlanta and Seattle. Minneapolis, where 46-year-old Floyd died, was reported to be relatively calm.
But in Seattle, Portland and Atlanta there were reports of tear gas being fired.
What have Floyd's family been saying?
Sixteen members of George Floyd's family joined the 60,000 protesters for the Houston rally.
They included sister La Tonya and brother Philonese. A nephew told the crowd: "Don't stop until we get justice for my uncle," the Houston Chronicle reports.
At an emotional news conference in Minneapolis, Roxie Washington, the mother of George Floyd's six-year-old daughter Gianna, said he was a good man.
Standing with Gianna, she said: "I'm here for my baby and I'm here for George because I want justice for him."
George Floyd's funeral is due to take place on 9 June in Houston.
Trump defends himself
President Donald Trump has meanwhile defended his controversial decision to pose with a Bible outside a historic church in Washington, whose basement was set on fire at the weekend.
Taking to Twitter, he wrote: "You got it wrong! If the protesters were so peaceful, why did they light the Church on fire the night before? People liked my walk."
On Monday, police used rubber bullets and smoke grenades to clear protesters from near the White House before Mr Trump stood for the cameras outside St John's Church.
Michael Curry, the presiding bishop of the Episcopal Church diocese in Washington, accused him of using the Church for "partisan political purposes".
Criticism also came from Washington's Catholic archbishop, who condemned Mr Trump's visit to the Saint John Paul II National Shrine on Tuesday. It "manipulated" the shrine, Archbishop Wilton D Gregory said.
Earlier, Democratic presidential hopeful Joe Biden criticised Mr Trump for using the crisis to appeal to his supporters, saying he was "serving the passions of his base".
On Monday, Mr Trump said he would deploy the army if cities and states failed to control the protests.
Monday night saw some of the worst unrest with widespread looting and arson as previously peaceful protests saw a minority resort to violence. In Las Vegas, a police officer was described on Tuesday as being in a grave condition after being shot.
Separately, an armed man was shot dead by police in the same city.
Four police were also shot in St Louis, though their injuries were not described as life-threatening. But a retired officer was shot and killed outside a looted store.
What's the background?
The protests began after a video showed Mr Floyd being arrested on 25 May in Minneapolis and a white police officer continuing to kneel on his neck even after he pleaded that he could not breathe.
