Dave Walton, deputy chief fire officer at West Yorkshire Fire and Rescue Service, hit out at a tweet from US President Donald Trump.

It said: “So horrible to watch the massive fire at Notre Dame Cathedral in Paris. Perhaps flying water tankers could be used to put it out. Must act quickly!”

Dave Walton shared the tweet with the message: “Of all the almighty half wits in all the world...your expertise in firefighting is on a par with your grasp of humility, equality and honesty.

“Arguably the most unwelcome and ill founded firefighting tip issued by anyone ever.”

In a later tweet, he said the thoughts of firefighters all over the world were with their Pompiers de Paris colleagues, particularly the firefighter who was seriously injured while tackling the fire.

Just under 400 firefighters tackled the fire through Monday night.
