London mayor Sadiq Khan on Sunday dismissed criticism from U.S. President Donald Trump over his response to Saturday's terror attack in London Bridge and Borough Market, the BBC reports.

Trump accused Khan of downplaying the attack by telling Londoners there was "no reason to be alarmed".

"We must stop being politically correct and get down to the business of security for our people," Trump tweeted on Saturday night, hours after the attack in which seven people were killed. "If we don't get smart it will only get worse."

Khan's team said on Sunday he had "more important things to do than respond to Mr. Trump", who they claimed had "deliberately" taken his remarks "out of context".

"The Mayor is busy working with the police, emergency services and the government to co-ordinate the response to this horrific and cowardly terrorist attack and provide leadership and reassurance to Londoners and visitors to our city," Khan's spokesperson added, according to the BBC.

During an interview earlier on Sunday, Khan had said: "Londoners will see an increased police presence today and over the course of the next few days. No reason to be alarmed."

"One of the things the police and all of us need to do is ensure that we're as safe as we possibly can be. I'm reassured that we are one of the safest global cities in the world, if not the safest global city in the world, but we always evolve and review ways to make sure we're as safe as we possibly can," he added.

The incident is not the first time that Trump and Khan have clashed.

During the presidential campaign last year, Trump first proposed a ban on Muslims entering the U.S., but suggested he could make an exception for Khan, who is London's first Muslim mayor.

Khan rejected the offer, saying: "It's not about me, it's about my friends, family and others from all around the world."

Khan also accused Trump of being "ignorant" about Islam and making both the U.S. and UK "less safe".

After his election, Khan accused then-Prime Minister David Cameron of using "Donald Trump playbook" tactics to try to divide communities in a bid to prevent his election.
