An Australian freelance photographer took the top prize in this year's World Press Photo competition

Warren Richardson's photo — of a man handing a baby under barbed wire on the Serbian-Hungarian border — is lit only by moonlight, as he didn't want to alert police to the location of the refugees he was following.

"I camped with the refugees for five days on the border. A group of about 200 people arrived, and they moved under the trees along the fence line. They sent women and children, then fathers and elderly men first. I must have been with this crew for about five hours and we played cat and mouse with the police the whole night. I was exhausted by the time I took the picture," he told the World Press Photo Foundation.

Richardson's photo was only one of many winners who were documenting the refugee crisis. But the photos covered a wide range of topics, including the Paris attacks, the earthquake in Nepal and protests in the US over police violence.
