From Haiti's devastating earthquake to war in Syria, Reuters photographers have covered the biggest news stories of the decade, capturing images of armed conflict, natural disasters, the plight of migrants and the drama of sport.
Yannis Behrakis led a team documenting Middle Eastern migrants arriving in Europe in 2015, capturing images of families on boats or their first steps on foreign land. The pictures saw Reuters jointly win the 2016 Pulitzer Prize for breaking news photography with The New York Times.
"We showed the world what was going on, and the world cared. It showed that humanity is still alive," Behrakis, who died in March, said at the time. "We made for these unfortunate people's voice to be heard."
"The semi-finals is a warm up also for photographers," said Kai Pfaffenbach, whose shot won third prize for the sports singles category at the 2017 World Press Photo awards.
"I was free to play around and I thought I would try a motion blur ... I saw him running ... The moment he turned his head I thought the picture was ruined as it would be too shaky but it just happened ... and overnight it became 'the' picture."
