The truck stopped in front of Bosnia's presidency where the people paying respect tucked flowers into its canvas. Among them was Fatima Aljic, whose son, husband and brother were killed in the massacre. Aljic is still searching for their remains.
"Every year I come to bid farewell to the victims and it is difficult — it is very hard," Aljic said before tearing up. "It would be hard even to witness what happened to us happening to someone else, let alone to experience it yourself."
The Srebrenica killings were the bloody crescendo of the war in Bosnia, which came after the breakup of Yugoslavia unleashed nationalistic passions and territorial ambitions that set Bosnian Serbs against the country's two other main ethnic factions — Croats and Bosniaks.
The massacre has been declared a genocide by international and national courts, but Serb leaders in Bosnia and neighbouring Serbia continue to downplay or even deny it despite the irrefutable evidence of what happened.
