London: British police yesterday said that officers had shot at a woman at a London address, arrested six others as part of counter-terrorism operations and averted an active terror plot. An operation across London and Kent, south-east England, was not linked with the arrest of a 27-year-old man with knives near the Houses of Parliament on Thursday, the Scotland Yard said yesterday.
