TOPSHOT - A flower left in tribute to the victims of the March 22 terror attack is seen next to the Palace of Westminster that houses the Houses of Parliament 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)
