The World Press Photo 2012 exhibition is on show at the Southbank Centre until 26 November. Taken by photojournalists all around the world, the photos show everything from the Syrian war to the London 2012 Olympics.
The winning press image was from Paul Hansen of the Swedish daily newspaper Dagens Nyheter. It shows a group of men carrying the bodies of two dead children through a street in Gaza City.
See the gallery above for our highlights of the shortlist – they’re pretty powerful.
