Following the attack on London Bridge at 10 pm local time, UK Prime Minister, Theresa May says the general election would go ahead as planned on June 8.
Most political parties suspended campaigns after three men drove a van into pedestrians on the London bridge and stabbed other victims at the nearby Borough market before they were shot dead by police.
Eye witnesses described the attackers as being on the rampage and hitting anyone on sight with knives.
The men were wearing fake explosive vests.
Police cars and cordons remain in the area.
Theresa May said full campaigning would resume on Monday.
In a speech on Sunday at Downing Street after an emergency security meeting, she promised to step up efforts to combat terrorism and to work with other countries to ensure the internet is not a safe space for terrorists.
She urged people to go about their daily activities normally.
Seven people have been killed and more than 40 were injured in the London attack which happened just two weeks after the Manchester Arena bombing that killed 22 people.
There have been three major attacks in the UK in less than three months.
Military officers were deployed to busy streets and major cities across the UK following the Manchester attack.
The country’s terror level remains at severe which implies an attack is highly likely.
