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’s spokesperson said the London Mayor’s thoughts were with the victims’ families and he “is not going to waste his time responding to this sort of tweet”.

His online feud with Trump dates back to just after Trump took office in 2016, when the Mayor called the President’s proposed Muslim immigration ban “divisive and outrageous”.

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.

“London needs a new mayor ASAP. Khan is a disaster will only get worse,” he said, while retweeting a message that highlighted two stabbings and a shooting in London in the last few days.

After the Islamic State claimed the 2017 London Bridge terrorist attack, Trump said Khan was guilty of “pathetic” behaviour and in July last year he claimed the Mayor had “done a very bad job on terrorism”.

Opposition Labour Party leader Jeremy Corbyn attacked the US President’s latest outburst, saying it was “absolutely awful to see Donald Trump using the tragedy of people being murdered to attack the Mayor”.

He tweeted: “Sadiq Khan is rightly supporting the police to do their job while Katie Hopkins spreads hateful and divisive rhetoric. They seek to divide at a time we need to come together.”

The Metropolitan Police said 14 people including several boys and a girl have been arrested in connection with the incidents of stabbing and shooting in Wandsworth, Plumstead and Clapham areas of London.
