The exhibition shows the winners of the World Press Photo competition, which this year attracted 103 481 images.
The 350 winners will all be displayed at show, at London’s Southbank Centre.
These include the overall winner – a photograph by Paul Hansen of Swedish newspaper Dagens Nyheter, which shows a group of men carrying the bodies of two dead children through the streets of Gaza City.
There was one UK winner this year, with Nadav Kander taking first prize in the staged portraits single category for his photo of actor Daniel Kaluuya.
Other winning photographs include images of the London 2012 Olympics in the sport category, while the contemporary issues category tackles subjects such as anti-austerity demonstrations in Spain and same-sex couples in Vietnam.
The World Press Photo Exhibition is at the Royal Festival Hall, Southbank Centre, London SE1, from 8-26 November. You can see more of the winning photographs here.
