Donald Trump stirs up feud with Mayor Sadiq Khan over attacks in London

US President Donald Trump further stirred up his ongoing feud with London Mayor Sadiq Khan by blaming him for a recent spate of stabbings and violence in the UK capital.

Trump and Khan have repeatedly clashed ever since the Pakistani-origin mayor questioned the red carpet being rolled out for the US President by Britain, most recently for a state visit hosted by Queen Elizabeth II earlier this month.

Khan has also likened Trump to "20th century fascists" for his divisive views on immigration, with Trump hitting back with social media messages about his "terrible job" as Mayor of London.
