The aftermath of an attack that shook the heart of London; a rioter on fire running from police in Venezuela; a young boy being pulled alive from rubble in Mosul and concertgoers hiding from a gunman at a country music festival in Las Vegas … these are just some of the powerful images that will be on display in a free exhibition at the Scottish Parliament, as part of World Press Photo Exhibition 2018 from Wednesday 1 August – Saturday 25 August.
