Following the “heartless and appalling” death of African-American man George Floyd, the protests are now giving "way to violent opportunism,” Sky News host Chris Kenny says.

Police and protesters are facing off in another night of unrest in the United States as violent demonstrations continue to erupt over the death of Mr Floyd.

Mr Floyd died after a Minneapolis police officer knelt on his neck for more than eight minutes as he told them "I can't breathe".

Nationwide protests have subsequently been sparked across the country, leading to violence, the burning of buildings and further deaths and arrests.

“There are so many acts of violence, so many horrific stories in cities across the US,” Mr Kenny said.

“And there is a lot of ill-informed, whether deliberate or not, commentary about this being the destruction of America, the inevitable result of Donald Trump's divisiveness”.

“Barack Obama had to deal with recurring race rights in Ferguson, Missouri, after another African American man, Michael Brown, was killed by police and those riots spread across the nation,” he said.

He said US President Donald Trump must now “check himself” and “make sure he doesn't tweet or do anything to make it worse”.

Last week, a Tweet by US President Donald Trump relating to "looting and shooting" and the violent protests in Minneapolis was 'hidden from view' on the social media platform with Twitter stating it violates rules about "glorifying violence".

“There is no doubt there is a partisan strain to all this, the left who first began violent protests against Trump the day he was elected, are certainly part of the push now, still taking out their frustrations again”.

“The question now is when and how it will stop, or at least subside?” Mr Kenny said.
