The lights of the Eiffel Tower were turned off at midnight to pay respect for the victims of Wednesday's vehicle and knife attack in Westminster.
Five people, including a police officer, were killed and more than 40 others were injured in the incident. The assailant was later shot dead. It is the first mass-casualty terrorist attack on Britain in over a decade, according to the Guardian.
People fled for their lives as a Hyundai 4x4 driven by the terrorist at about 2.40pm indiscriminately ran into people on Westminster Bridge. The vehicle then careered off the road on to pavement a few metres away from Big Ben and the attacker tried to storm parliament armed with a knife.
Moments later, a police officer who was guarding parliament was fatally stabbed. The attacker, dressed in black, was shot by another armed officer and died of his injuries.
