A picture shows red London buses, pedestrians and traffic crossing Westminster Bridge over the River Thames with the Union flag atop the Houses of Parliament (R) flying at half-mast in central London on March 23, 2017. 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. / AFP PHOTO / Niklas HALLE'N (Photo credit should read NIKLAS HALLE'N/AFP/Getty Images)
