Enough is enough: British PM

British prime minister Theresa May has said "it is time to say enough is enough" as she condemned a terror attack on "innocent and unarmed civilians" which left seven people dead and 48 injured in London.

A white van hit pedestrians on London Bridge at about 22:00 BST on Saturday, then three men got out and stabbed people in nearby Borough Market. The three attackers, who wore fake bomb vests, were shot dead by police. Several arrests have been made after police raids in Barking, east London.  

Most political parties have suspended national general election campaigning, but May said full campaigning would resume on Monday and the general election would go ahead as planned on Thursday.

May said Britain is experiencing a new trend of "brutal terror". She added the suspects wore fake suicide vests to "spread panic and fear". "We cannot and must not pretend that things can continue as they are," she said.  "Things need to change, and they need to change in four important ways."

Eyewitnesses to the attack described seeing a white van travelling at high speed along London Bridge, hitting pedestrians, before crashing close to the Barrowboy and Banker pub. BBC reporter Holly Jones, who was on the bridge, said it was "probably travelling at about 50 miles an hour" and hit "five or six people".

Three men then got out and began attacking people in the nearby market - an area known for its bars and restaurants, which were busy on a warm summer evening. Terrified drinkers rushed away from the scene, some taking shelter in London Bridge Underground station.

One witness, Gerard, told the BBC he saw a woman being stabbed "10 or 15 times" by men shouting "This is for Allah". Another, Eric, told the BBC the men "ran towards the people that they nearly ran over". 

"I thought, 'Oh maybe they're worried about them and trying to comfort them...' "[Then] they literally just started kicking them, punching them, they took out knives... it was a rampage really."

Metropolitan Police Commissioner Cressida Dick praised the "extraordinary bravery" of her officers, on and off duty, who risked their lives by rushing to confront the attackers. 

More than 80 medics were sent to the scene. The injured, some of them in critical condition, are being treated in five London hospitals

The Met Police has set up a casualty bureau on 0800 096 1233 and 020 7158 0197 for people concerned about friends or relatives Two Australian citizens "have been directly impacted," says the country's Prime Minister Malcolm Turnbull. Four French citizens have been injured, one seriously, according to foreign minister Jean-Yves Le Drian

Speaking in Downing Street after a meeting of the government's emergency Cobra committee, the prime minister said the country "cannot and must not pretend that things can continue as they are". "We believe we are experiencing a new trend in the threat we face as terrorism breeds terrorism," she said. May said the UK's counter-terrorism strategy would be reviewed, as she promised to step up efforts to combat Islamist ideology and work with other countries to prevent the internet being a "safe space" for terrorists.

She said there was "too much tolerance of extremism in our country" and while it would involve "some difficult and embarrassing conversations", that must change. "It's time to say enough is enough," she added. The country's terror level remains at severe - meaning an attack is highly likely - but has not been raised to critical as it was after the Manchester Arena bombing. 

Jeremy Corbyn described the attack as "brutal and shocking". Sadiq Khan has said he believes the threat of terror attacks are "part and parcel of living in a big city" and encouraged Londoners to be vigilant to combat dangers. The Mayor of London revealed he had a "sleepless night" after the recent bombing in New York, and said major cities around the world "have got to be prepared for these sorts of things" to happen when people least expect them.

Harun Khan, Secretary General of the Muslim Council of Britain, said he was "appalled and angered" by the attack.

Muslims everywhere are outraged and disgusted at these cowards who once again have destroyed the lives of our fellow Britons. 

The police are asking anyone with photographs or videos of the incident to upload them here. With three attacks in close proximity, terrorism against soft targets is beginning to feel, to some people, like the new normal. 

The brutal reality is that this kind of threat is absolutely typical of what jihadists sought to achieve in all their attacks across Europe.

Since 2013 security services in the UK have foiled 18 plots.
