Belgian Parliament held a minute of silence on Thursday (March 23) to honour the victims of Wednesday's attack in London which killed four people, including the attacker, and injured about 40 more. <br /> <br />British-born Khalid Masood, who was once investigated by intelligence officers over concerns about violent extremism, sped across Westminster Bridge in a car, ploughing into pedestrians. He then ran through the gates of the nearby parliament building and fatally stabbed an unarmed policeman before being shot dead. <br /> <br />It was the deadliest attack in Britain since 2005, when 52 people were killed by Islamist suicide bombers on London's public transport system. <br /> <br />The attack took place on the first anniversary of attacks that killed 32 people in Brussels, and resembled Islamic State-inspired attacks in France and Germany where vehicles were driven into crowds.
