British Police Say Active Terrorism Plot Foiled; Woman Shot In Raid

British police officers secure a cordon in a residential street in northwest London on April 28.

After an armed raid on a house in London, British police say they have thwarted an active terrorism plot.

Neil Basu, senior national coordinator for counterterrorism policing, said six people were arrested in an operation during which counterterrorism officers used tear gas while storming a house in north London.

A woman in her 20s was shot during the raid on the evening of April 27. Basu said searches were ongoing and that police believed they had contained the threat.

Asked by journalists whether the authorities had foiled an active plot, Basu replied, "Yes."

Meanwhile, a man who was arrested carrying knives near Prime Minister Theresa May's office on April 27 in a separate incident remains in police custody, Basu said.
