Seven people have died and fifty more have been injured in a terrorist attack near the busy London Bridge Station in the center of the British capital late Saturday, Metropolitan Police have confirmed, the latest in a string of attacks that has gripped the nation over the past three months.

U.K. Prime Minister Theresa May condemned the attack in a statement outside Downing Street early Sunday, and vowed that the country's general election would take place as scheduled on June 8, although both of the main political parties would suspend campaigning for the day. 

"Enough is enough," May said in a strongly-worded response to last night's incident in which she hinted at a change in approach to those suspected of radicalising young men and women towards terror.

"There is far too much tolerance of extremism in our country ... we cannot and must not pretend that things can continue as they are."

Police say three men drove a white transit van at speed towards London Bridge just after 10:00 pm local time, deliberately targeting pedestrians before continuing to the busy restaurant and pub district of Borough Market, which was packed with revellers enjoying the unusually warm summer Saturday evening.

The attackers, who were armed with knives and wearing vests with replica explosives attached, then attacked people at random, killing six before armed police officers shot them dead at the scene. The police response came within 8 minutes of the original point of attack.

The Met Police also noted that their investigations were ongoing.

"The investigation is being led by the Counter Terrorism Command and we would ask anybody who has images or film of the incident to pass those to police by uploading it at www.ukpoliceimageappeal.co.uk," New Scotland Yard said in a statement. 

"We are reviewing and planning to strengthen our policing stance across London over the forthcoming days, and there will be additional police and officers deployed across the Capital."

U.K. Prime Minister Theresa May said late Saturday that the ongoing incidents in central London is being treated as terrorism, a view the Met Police confirmed shortly afterwards.

May chaired a meeting of senior members of government and security officials, known as a COBRA meeting, early Sunday morning in London but did not alter the country's terrorist threat level.

The U.K.'s terror alert level was reduced to "severe" from "critical" last week after a number of arrests were made in connection with the deadly attack at the conclusion of an Ariana Grande concert at the Manchester Arena on May 22.

Britain is also in the midst of a general election campaign, with voters slated to head to the polls on June 8 after Prime Minister Theresa May announced the snap poll on April 18.

All political parties have agreed -- for the second time since the election was called -- to suspend campaigning while the Prime Minister meets with security officials. 

Last night's attack follows the bombing of an Ariana Grande concert in Manchester Arena on May 22, which killed 22 people, including an 8-year old schoolgirl, and injured scores more. 

It also had echoes of the March 22 incident outside the U.K. Houses of Parliament, were a lone terrorists killed four people in a car-and-knife attack during the mid-day rush hour along Westminster Bridge.
