Thousands have gathered in the northeast Bosnian town of Kalesija to bury the remains of 32 Muslim Bosniaks killed by Bosnian Serb forces at the start of the country's 1992-95 war.

They were victims of a brutal campaign to remove the non-Serb population from the nearby town of Zvornik and other areas the Serbs controlled.

The campaign included killings, expulsions and detention in concentration camps until no non-Serbs were left in the once-mixed town.

The bodies of the victims were found in mass graves, identified through DNA analysis and buried at a cemetery in Kalesija where hundreds of victims previously found already have been laid to rest.

A total 1,998 people were killed in Zvornik during the campaign. The bodies of 611 are still missing.
