A vigil is being held in Trafalgar Square for the victims of Wednesday's terror attack in London.
People gather for a vigil in Trafalgar Square in central London on March 23, 2017 in solidarity with the victims of the March 22 terror attack at the British parliament and on Westminster Bridge.
Britain's parliament reopened on Thursday with a minute's silence in a gesture of defiance a day after an attacker sowed terror in the heart of Westminster, killing three people before being shot dead. Sombre-looking lawmakers in a packed House of Commons chamber bowed their heads and police officers also marked the silence standing outside the headquarters of London's Metropolitan Police nearby.
