Several campaign groups and charities including Avaaz and Amnesty International organised a rally outside Downing Street in London to call on the British government to set out a plan to protect Syrian children in the embattled Syrian city of Aleppo. Hundreds of wounded civilians were stranded in rebel-held areas of Syria's Aleppo on October 22 after the UN said security concerns had prevented evacuation convoys even as Russia extended a ceasefire into a third day. / AFP PHOTO / Daniel Leal-Olivas
