Ron Haviv started his career as a photojournalist in 1989 in Panama and there he took a photo showing the country's future vice-president being beaten by a paramilitary.

US President George Bush used it to justify the US invasion.

After Panama he went to Bosnia, where in 1992, he took another iconic photograph, which shows Serbian paramilitary soldiers kicking the bodies of civilians they had just killed. That photograph was used to indict their leaders for war crimes.

A quarter of a century later, Ron is working on a documentary about the lives that these two photographs took once they left his camera.
