US President Donald Trump has visited Kenosha, Wisconsin, to back law enforcement after the police shooting of a black man sparked civil strife.

The Republican president blamed "domestic terror" for the "destruction" in the Midwestern city.

Kenosha saw days of violence after police shot Jacob Blake in the back and left him paralysed on 23 August.

Opinion polls show Mr Trump is narrowing Democratic rival Joe Biden's lead ahead of November's election.

The president is pushing a strong "law and order" message. Mr Biden has accused Mr Trump of stoking racial division.

"Fires are burning and we have a president who fans the flames rather than fighting the flames," the former US vice-president said ahead of Tuesday's trip.

What did Trump say in Kenosha?

The president visited areas damaged in the protests, including a burnt-out furniture store destroyed in the upheaval.

"These are not acts of peaceful protest, but really domestic terror," he told local business leaders at a round table meeting in a high school gym.

Mr Trump defended the actions of US police and accused the media of focusing only on "bad" incidents involving officers.

"You have people that choke," he said. "They are under tremendous pressure. And they may be there for 15 years and have a spotless record and all of a sudden they're faced with a decision. They have a quarter of a second to make a decision. And if they make a wrong decision, one way or the other, they're either dead or they're in big trouble.

"And people have to understand that. They choke sometimes."

The president did show some empathy for those hurt in confrontations with police, saying he felt "terribly for anybody who goes through that". But he said he did not believe there was systemic racism in law enforcement.

Mr Trump said he sent the National Guard into Kenosha, though they were deployed by Wisconsin's governor and supported by 200 federal law enforcement officials ordered in by the president.

He also said his administration would provide nearly $4m (£3m) to help Kenosha businesses that had been damaged in the riots and $1m for city law enforcement.

Demonstrators have accused outside agitators of violently hijacking their protests. Kenosha police said at the weekend that 105 out of 175 suspects arrested during the unrest came from outside the city.

Why didn't Trump meet the Blake family?

The president said he did not meet the Blake family because they had wanted lawyers present.

Mr Trump instead said he was honoured to have the African-American co-pastors of Mr Blake's mother at the roundtable.

Co-pastor Sharon Ward said: "I think it's important to have black people at the table to help solve the problem."

Earlier in an interview with CNN, Mr Blake's father, Jacob Blake Snr, said his son's life was more important than a meeting with President Trump.

"I'm not getting into politics. It's all about my son, man. It has nothing to do with a photo op," he said.

Mr Blake Snr said his son was still paralysed from the waist down, "holding on for dear life".

A police officer shot Jacob Blake seven times in the back during an arrest as the 29-year-old tried to get into a car where his three children were seated.

How did Democrats react to the visit?

Mr Trump's visit to Kenosha went ahead despite appeals from the Democratic mayor and governor to stay away.

Over the weekend Kenosha Mayor John Antaramian said it was not a good time for Mr Trump to visit.

"Realistically, from our perspective, our preference would have been for him not to be coming at this point in time," he told National Public Radio.

Wisconsin's Democratic Governor Tony Evers also warned against the visit, saying it would "hinder our healing".

Congressman Mark Pocan, a Wisconsin Democrat who grew up in Kenosha, said on Twitter the president visited the city "to spread hate".
