WASHINGTON President Trump responded to the terror attacks in London by taking aim at Londons mayor, political correctness and gun control.

In a series of early morning tweets, the president derided and misrepresented Mayor Sadiq Khan's attemptto calm Londoners after the third terror attack in Britain in less than three months.

At least 7 dead and 48 wounded in terror attack and Mayor of London says there is "no reason to be alarmed!" said Trump.

In responding to the attacks, Khan told Londoners theres no reason to be alarmed by an increased police presence over the coming days while vowing of the terrorists that we will never let them win.

We must stop being politically correct and get down to the business of security for our people. If we don't get smart it will only get worse, Trump said on Twitter. On Saturday night, police said sevenpeople died and at least 48 were injured after a van plowed into pedestrians on London Bridge and assailants went on a stabbing rampage at nearby Borough Market.

In a final tweet, Trump also seemed to blast the gun control debate in the United States. Do you notice we are not having a gun debate right now? That's because they used knives and a truck! said Trump.

Britain has stricter gun laws than in the U.S. and prohibits semi-automatic rifles. In 2011, the U.K. had0.07 gun homicidesfor every 100,000 people; the U.S., by contrast, had 3 gun homicides for every 100,000.Further, the U.S. permits individuals on its terror watch list equal gun rights, including purchasing high-capacity weapons like the one Omar Mateen used last year to kill 49 people at an Orlando night club.

Trump's criticism of the mayor drew fire from Republicans in the U.S., including Doug Heye, a strategist and former top aide to House Republican leadership.

"I can't imagine Theresa May tweeting like this to the mayor of Orlando or San Bernadino," said Heye.
