Police cordon off the street of terraced houses in east London
A man seen carrying a gun has been shot dead in the street by police in east London.
The BBC's Home Affairs correspondent Danny Shaw said police were called to Honeysuckle Close, in Harold Hill, Romford at 1340 GMT.
They were responding to an apparent domestic dispute between a man and a woman.
Police requested support from armed officers after neighbours said the man was spotted with a gun.
Police say the man was standing in the street when shot and also said they recovered what appear to be firearms at the scene.
A Metropolitan Police spokeswoman said: "Police were called at 1340 to an address in Romford to reports of a domestic violence incident.
"Police received reports from the public of a man seen in possession of a firearm. Armed officers attended at the request of borough officers.
"A man has been shot in the street by police. He was pronounced dead at a local hospital."
A woman was taken to hospital with non-life threatening injuries which police say are related to the domestic violence, not the shooting.
Both the Directorate of Public Standards and the Independent Police Complaints Commission have been informed.
One neighbour in Honeysuckle Close, who did not want to be named, said: "I saw the police here and I just stayed out of the way.
"They blocked the square off and the helicopter was overhead."
Arthur Collins, who works at The Saxon King pub in nearby Petersfield Avenue, said: "We've just heard about it, but we don't know any details.
"It's a bit of a shock. I've lived around here for 22 years and it's a nice area."
The IPCC confirmed that its investigators were looking into the shooting.
An IPCC spokeswoman said: "We are aware of a fatal shooting of a man in Romford by officers from the Metropolitan Police Service today, Wednesday 29 October.
"IPCC investigators are currently on their way to the scene and will assess the circumstances this afternoon.
"No further information is available at this stage."
