London Mayor Sadiq Khan dismissed President Donald Trump’s “ill-informed” tweet and criticism about him after the London Bridge terror attack Saturday. Khan’s spokesman said the mayor has “more important things to do” than respond to Trump’s tweet.

“The Mayor is busy working... to coordinate the response to this horrific and cowardly terrorist attack,” Khan's spokesman said, adding “He has more important things to do than responding to Donald Trump's ill-informed tweet that deliberately takes out of context his remarks urging Londoners not to be alarmed when they saw more police - including armed officers - on the streets.”

During an interview early Sunday, Khan 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 to make sure we are 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.

Trump on Sunday criticized Khan’s comments and his assurance about an increased police presence in the city following the third deadly attack in the past three months there, and argued on Twitter that leaders should “stop being politically correct” and focus on “security for our people.”

Seven people were killed and several injured Saturday in London after a vehicle drove at high speed into pedestrians on London Bridge. Soon after, the attackers started targeting random people on the street, especially those returning home from bars in the nearby Borough Market area.

In a series of tweets late Saturday and early Sunday, Trump promoted his stalled travel ban, expressed his opinions on gun control supporters and promised that the U.S. will be there to support London and the U.K.

“The United States condemns the cowardly attacks targeting innocent civilians in London this evening. We understand the U.K. police are currently treating these as terrorist incidents. The U.S. stands ready to provide any assistance authorities in the U.K. may request. Our hearts are with the families and loved ones of the victims. We wish a full and quick recovery to those injured in the attacks. All Americans stand in solidarity with the people of the United Kingdom,” a statement by the Department of State said.

Trump criticized Khan for saying there was “no reason to be alarmed.” He dedicated one tweet to specify the number of causalities and injured and then went on to say that the mayor still said there was no reason to be alarmed.

Trump’s first comment after the attack came late Saturday in a tweet where he pushed his proposed travel ban. Trump’s ban barred visitors from six mostly Muslim countries and refugees from around the world, which has been temporarily blocked by several U.S. courts.

“We need to be smart, vigilant and tough. We need the Travel Ban as an extra level of safety!” Trump tweeted Saturday after the attack.

The Trump administration last week also formally asked the Supreme Court to allow the ban to take effect, arguing that restricting immigration by refugees and visitors from the six specified countries included in his ban, is essential to protect the national security of the country.
