The white supremacist teenager who shot dead 10 people in Buffalo, New York, had earlier called for the murder of London mayor Sadiq Khan in a manifesto. Mr Khan said: “One the things we do know is that these terrorists want to discourage people of colour, women, Muslims to stand for public office”. The Mayor of London added: “We’ve got to make sure that we respond in a way that says ‘no’ to these terrorists even thinking they can be successful”. Report by Jonesia.
