Boom. Come over here, - Trump comments on 2015 terrorist attack in Paris

Trump's NRA speech also drew anger in France on Saturday, after the USA president, using his hand in a gun gesture, acted out how a gunman had killed hostages one by one during an attack in Paris in November 2015.

U.S. President Donald Trump speaks at the NRA-ILA Leadership Forum during the NRA Annual Meeting & Exhibits at the Kay Bailey Hutchison Convention Center on May 4, 2018 in Dallas, Texas.

London's doctors, politicians and health care supporters mocked US President Donald Trump on Saturday for telling the US National Rifle Association that an unnamed London hospital had "blood all over the floors" from an epidemic of stabbings, suggesting countries with tough gun laws have just as much violent crime as the US.

"They took their time and gunned them down one by one - boom, come over here, boom, come over here, boom", he said. "They captured them and killed one after the other - boom, boom", Come here, let's boom boom!"

In a statement Saturday, Le Drian said gun violence statistics "do not lead us to reconsider France's choice on this issue".

"There is more we can all do to combat this violence, but to suggest that guns are part of the solution is ridiculous".

"The free flow of arms within society does not constitute a bulwark against terrorist attacks, it can instead facilitate the planning of this type of assaults", the ministry fired back. The series of terrorist attacks France has experienced in recent years have also been the worst massacres in the country since 1945.

The comments from Trump came less than a week after French President Emmanuel Macron visited Washington as guest of honour for a state visit which saw both of the leaders eager to stress their friendship.

Other victims including Emmanuel Domenech wrote expletive-filled messages directed at the USA president on Twitter.

Writing on Twitter, he said: "Donald Trump's shameful comments and obscene mockery speak volumes about what he thinks of France and its values".

Valls simply said of Trump's remarks: "Indecent and incompetent. What more is there to say?"

Mr Trump, who is due to visit Britain on July 13, told NRA members that a "once very prestigious" London hospital, which he did not name, had become overwhelmed with knife attack victims. "They took their time and gunned them down one by one", Trump was quoted by AFP as saying.

He then mimicked someone using a knife.

The incident which witnessed over 130 deaths and 368 people injured is touted to be one of the deadliest attacks in French history. The first lady's spokeswoman, Stephanie Grisham, says the focus will be on the overall wellbeing of children, which Mrs Trump has spoken about since becoming first lady.
