A woman has been shot by police and is under armed guard in hospital following an anti-terrorism raid in north-west London yesterday.

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.

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 has not been revealed.

As part of the operation in London and Kent, 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 other addresses across the capital.

The arrests are not connected to an incident yesterday near Downing Street.

In a separate investigation, a man is being held under the Terrorism Act after he was found carrying a rucksack containing several knives just yards from Downing Street.

It's understood the arrest of the 27-year-old suspect yesterday was 'intelligence-led.'
