Twenty-fours on from the terror attacks on Westminster, the world remains in shock at the violence which unfolded in central London.
At least four people have been killed and forty injured after 52-year-old attacker Khalid Masood mowed down pedestrians on Westminster Bridge, before getting out of the car and stabbing a policeman.
Theresa May said the attacker, who was shot dead by police, was British-born and had previously been investigated by MI5. Islamic State has claimed responsibility for the attack.
