In a series of early morning tweets, Mr. Trump also pours scorn on London Mayor Sadiq Khan's attempt to reassure the public after three assailants smashed a van into pedestrians on London Bridge on Saturday then attacked revellers with knives.

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

In another tweet, Mr. Trump derided gun control advocates.

"Time to say enough is enough"

Britain's general elections will go on as scheduled, British Prime Minister Theresa May said on Sunday while addressing the media after the emergency COBRA meeting in the aftermath of the London terror attack. "As a mark of respect, the two national parties have suspended their campaigns but violence can never be allowed to disrupt life," she said, adding that campaigns will resume on Monday.

Ms. May said the nation "must come together, pull together" and "united, we will take on and defeat our enemies". She said that security services had disrupted five credible terror plots since the Westminster attack in March. "We cannot, must not pretend that this can continue," she added.

Ms. May also called for tougher measures to counter terrorism at home, both on the ground and in cyberspace. "We cannot allow this ideology [Islam] the safe space it needs to breed - but that is what internet provides. We need to reach international agreements that regulate cyberspace and do everything we can at home to reduce this threat," she said. "But we must not forget about safe spaces that continue to exist in real world.Significant progress has been made in recent years, but there is too much tolerance of extremism in recent years. We have a robust counter-terrorism strategy, but as the nature of threat becomes more complex, strategy needs to keep up."

"These [Westminster, Manchester and London bridge] attacks are not connected by a common network, but connected by this - single Islamist ideology that claims western values are incompatible with values of Islam, an ideology that is a perversion of Islam. Defeating this ideology is one of the great challenges of our time. It can only be defeated if we turn people's lives away from this violence," she added.

She added that police patrols will be increased in London, including those by armed officers.

1.45 p.m.: Horrified witnesses of the terror attacks narrated tales of the gruesome events that unfolded when three knife-wielding men mowed down people and launched a stabbing spree when many were out for dinner or drinks in restaurants and pubs.
