Photos taken by Bosnian Damir Sagolj documenting the persecution of the Rohingya ethnic minority in Myanmar were part of a series of photographs that won the Reuters news agency one of their two 2018 Pulitzer Prizes on Monday.

The news agency was recognized for its international reporting on the methods of police killing squads in the Philippines, and for feature photography documenting the Rohingya refugee crisis in Myanmar and Bangladesh.

The Pulitzer prize is considered the most prestigious award in American journalism.

“In a year in which many Pulitzer prizes were rightly devoted to US domestic matters, we’re proud at Reuters to shine a light on global issues of profound concern and importance,” said Reuters Editor-in-Chief, Stephen J. Adler.

Four of the photos showing the violence endured by the Rohingya, a Muslim minority, as they are fled Myanmar for Bangladesh, were taken by Sarajevo-born Damir Sagolj, who was also the 2017 Reuters Photojournalist of the Year.

“The extraordinary photography of the mass exodus of the Rohingya people to Bangladesh demonstrates not only the human cost of conflict but also the essential role photojournalism can play in revealing it,” Adler said.

“We all like awards, but I am especially fond of those that are not for some ‘incident’(…) but for the best job done over a certain period of time,” Sagolj said. “These kind of awards are more important to me than those given for luck or instant inspiration.”
