A woman has been shot by police and four people were arrested during an anti-terror operation in north west London and Kent.
Armed officers entered a property in Harlesden Road, Willesden, shortly before 7pm on Thursday evening.
During the raid the woman, who was among a number of people under investigation, was shot. No other people were injured.
In unverified footage from the scene, specialist firearms officers can be seen outside a house and several gunshots were heard.
The woman, aged in her 20s, was taken to hospital where she is under police guard.
Police said she has not been arrested "at this time" due to her condition, which is said to be 'serious but stable'.
As part of the operation, four people have been arrested on suspicion of terror offences.
A 16-year-old youth and a woman, 20, were detained at the property, while a 20-year-old man was arrested nearby.
A 43-year-old woman was held in Kent a short while later.
They are in custody at a south London police station.
Police said the Willesden property and people connected to it had been "under observation by counter-terrorism officers as part of an ongoing intelligence-led operation".
Detectives are carrying out searches there as well as at other addresses across the capital.
The shooting has been referred to the Metropolitan Police's Directorate of Professional Standards as well as the Independent Police Complaints Commission.
The raid was not connected to the arrest earlier in the day in Whitehall of a man who police say was carrying a rucksack containing several knives.
