British Army soldiers patrol along Whitehall near Downing Street and the Houses of Parliament in central London on May 24, 2017. Britain deployed soldiers to key sites Wednesday and raised its terror alert to the maximum after the Manchester suicide bombing by Salman Abedi, reportedly a Briton of Libyan descent, who may have been radicalised in Syria. Prime Minister Theresa May announced that the army would be deployed on the streets to support armed police under a plan codenamed Operation Temperer, which was developed in the aftermath of the November 2015 Paris terror attacks. / AFP PHOTO / Justin TALLIS
