Serbian Prime Minister Aleksandar Vucic arrived on Saturday to Srebrenica to attend a ceremony marking the 20th anniversary of the massacre committed in the Bosnian town by Bosnian Serb forces.

Upon the arrival at a memorial complex, Vucic was briefly booed by a group of participants of the ceremony before he entered a hangar where he was to sign a book of condolences, according to an AFP journalist. He also spoke with female relatives of the victims, of whom one give him a long hug.

In a statement released shortly before his arrival,  Vucic condemned the "monstrous crime" that saw  some 8,000 Bosnian Muslim boys and men slaughtered by Bosnian Serb forces after they captured the town in July 1995, near the end of Bosnia's inter-ethnic war.
