London has been rocked by a string of deadly terror attacks in recent weeks.
The first, in which a van ploughed into pedestrians on Westminster Bridge in March, left six dead.
Then, just last month, a suicide bomber struck a mosque in the heart of the capital, killing 52 people.
But the scale of the attack is far less concerning than the scale and timing of the attacks.
The latest to hit London, the Westminster Bridge attacks have seen a spike in violence.
The attackers were all born and raised in the capital.

The driver, a Pakistani national from Pakistan, was killed in the attack.
There has been an increase in attacks in the past month, with four people killed in a series of car and knife attacks in London, Manchester and Liverpool.
A fifth person was injured when a man drove a car into a crowd on Westminster’s Westminster Bridge.
It is unclear if the attacker who drove his car into pedestrians was inspired by Islamic State, but the UK government has been under fire for failing to stop the growth of extremism and terrorism in the country.
This is what the UK looks like: It appears that UK has become a dangerous place to live.
Britain has the third highest number of foreign-born people in the world and the highest percentage of Muslim-origin people living in Britain.
The British capital is also home to more than 200 Islamic State training camps, including one in Wapping.
But the capital’s police have struggled to contain the spike in violent crime.
London Mayor Sadiq Khan said on Thursday he had ordered an urgent review of security measures at London’s new airport after three men were arrested after planning to detonate explosives in a train.
“There has to be a level of vigilance in every city,” Khan said.
“There has got to be more than just the military.”
He added: “We will do everything we can to make sure that this kind of activity doesn’t occur in the future.”
The first attack in the UK, in March 2016, was also a vehicle attack.
