Protests have erupted in the US state of Wisconsin after police shot a black man many times while responding to what they said was a domestic incident.
The man, identified as Jacob Blake, was taken to hospital for surgery and is now in intensive care, his family said.
Video posted online appears to show Blake being shot in the back as he tries to get into a car in Kenosha, reports the BBC.
Authorities in the city declared an emergency overnight curfew after unrest broke out following the shooting.
Hundreds of people marched on police headquarters on Sunday night. Vehicles were set on fire and protesters shouted “We won’t back down”.
In a public safety alert, police urged 24-hour businesses to consider closing because of “numerous” calls about armed robberies and shots being fired.
On Twitter, President Donald Trump’s son Donald Trump Jr decried the protests as “anarchy”, and reposted a series of videos depicting burning buildings and cars, purportedly filmed in Kenosha.
Officers used tear gas to try to disperse hundreds of protesters who defied the county-wide curfew, which is in place until 07:00 on Monday (12:00 GMT).
Wisconsin Governor Tony Evers condemned the shooting of Blake, who was reportedly unarmed.
“While we do not have all of the details yet, what we know for certain is that he is not the first black man or person to have been shot or injured or mercilessly killed at the hands of individuals in law enforcement in our state or our country,” he said in a statement.
“I have said all along that although we must offer our empathy, equally important is our action. In the coming days, we will demand just that of elected officials in our state who have failed to recognise the racism in our state and our country for far too long.”
Jacob Blake’s name was trending on social media and thousands signed a petition calling for the officers involved to be charged. He is now out of surgery and in stable condition, according to family and friends on social media.
The shooting comes amid heightened tensions in the US over racism and police brutality following the death of African-American man George Floyd earlier this year.
Democratic presidential nominee Joe Biden on Monday released a statement calling for a “full and transparent investigation” of the shooting.
“This morning, the nation wakes up yet again with grief and outrage that yet another Black American is a victim of excessive force,” Biden said. “The officers must be held accountable.”
Kenosha Police Department said the “officer involved shooting” happened shortly after 17:00 on Sunday. It added that officers had provided “immediate aid” to Blake, who was taken to a hospital in Milwaukee in serious condition.
It said police had been responding to a “domestic incident” but gave no details about what led to the shooting. It is so far unclear who called police and what happened before the video recording began.
