At least five people were killed, including the assailant, and about 40 were injured in London on Wednesday after a car ploughed into pedestrians and a suspected Islamist-inspired attacker stabbed a policeman close to Britain's parliament. The casualties include 12 Britons, three French children, two Romanians, four South Koreans, one German, a Pole, one Chinese, an American and two Greeks.

The Westminster Bridge and the area just around parliament remained cordoned off on Thursday morning. Prime Minister Theresa May condemned the attack as "sick and depraved". "The location of this attack was no accident," she said in a statement outside her 10 Downing Street office late on Wednesday evening.

Members of the public were seen paying floral tributes to police officer Keith Palmer, who was stabbed to while on duty. Police have said that they were treating the attack as terrorism and have already arrested eight people at six locations in London and Birmingham in the investigation into the lone-wolf attack. The threat level for international terrorism in the UK was already listed at severe, meaning an attack was "highly likely."

A Reuters photographer saw at least a dozen people injured on the bridge. His photographs showed people lying on the ground, some of them bleeding heavily and one under a bus. In this gallery, IBTimes Singapore will show you a few of those heartbreaking images of the deadly terrorist attack.
