A young child was among four people hurt in a shooting in north London, police have said.
Shots were fired in Energen Close, Harlesden, at about 21:45 BST, Scotland Yard said.
The child and a man were taken to hospital with gunshot injuries, the Metropolitan Police confirmed. Both are in a critical condition. Another male victim and a woman sustained non life-threatening injuries, the force said.
No arrests have been made and police have appealed for witnesses to come forward. A Section 60 order was in place for the borough of Brent until 07:00, and a dispersal zone has been authorised for the Harlesden area, the force added.
Forensic officers continue to examine the scene and there will be additional police patrols in the area overnight.
Thousands of people have joined a protest in London over the death of African-American George Floyd in US police custody nine days ago.
It comes as UK chief constables said they stand alongside all those “appalled and horrified” by his death. In a joint statement, they said the right to lawful protest was a “key part of any democracy”. But they stressed coronavirus restrictions, including not gathering in groups of more than six, remained.
Protests began in the US after a video showed Mr Floyd, 46, 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. Prime Minister Boris Johnson said on Wednesday that Mr Floyd’s death had been “appalling” and “inexcusable”, but was criticised for failing to comment on the killing before now. SNP Westminster leader Ian Blackford said the UK government had “shuttered itself in the hope no-one would notice”.
British soldiers who have been accused of committing war crimes in Iraq are unlikely to face criminal prosecution.
Independent investigators were asked to look at thousands of allegations made against the British military after the invasion of Iraq in 2003. But the director of the Service Prosecution Authority (SPA) said just one remaining case was being examined.
Andrew Cayley said the “low level” of offending and lack of credible evidence had led most cases to be dismissed.
Mr Cayley said most of those cases were sifted out at a very early stage because of the lack of credible evidence or because the offending was “at such a very low level”.
More than 1,000 cases were made by former lawyer Phil Shiner and his firm Public Interest Lawyers (PIL). In 2017 he was struck off as a solicitor after a tribunal found him guilty of misconduct and dishonesty, including false accounts about the actions of UK soldiers.
President Donald Trump has threatened to send in the military to quell growing civil unrest in the US over the death of a black man in police custody.
He said if cities and states failed to control the protests and “defend their residents” he would deploy the army and “quickly solve the problem for them”.
Protests over the death of George Floyd have escalated over the past week.
On Tuesday the Las Vegas sheriff said an officer died in a shooting after police attempted to disperse a crowd. Dozens of people have been injured as authorities used tear gas and force to disperse protests which have swept more than 75 cities.
Four officers meanwhile were shot and injured on Monday night during unrest in St Louis, Missouri. Dozens of major cities have imposed overnight curfews.
Violence has erupted in cities across the US on the sixth night of protests sparked by the death in police custody of African-American George Floyd.
Dozens of cities imposed curfews, but many people ignored them, leading to stand-offs and clashes. Riot police faced off with protesters in New York, Chicago, Philadelphia and LA, firing tear gas and pepper bullets to try to disperse crowds. Police vehicles were set on fire and shops were looted in several cities.
The country is experiencing the most widespread racial turbulence and civil unrest since the backlash to the assassination of Martin Luther King in 1968.
The outpouring of anger began last Tuesday, after a video showed Mr Floyd being arrested in Minneapolis and a white police officer continuing to kneel on his neck even after he pleaded he could not breathe and fell unconscious.
