Thousands of people from around Bosnia and abroad gathered in Srebrenica on Tuesday for the annual ritual of commemorating the 1995 massacre in the eastern town and to give a dignified burial to the victims unearthed from mass graves and only recently identified through DNA analysis.

Twenty-eight years after they were brutally murdered in Europe’s only acknowledged genocide since the Holocaust, 27 men and three teenage boys will be laid to rest Tuesday at a vast and ever-expanding memorial cemetery just outside Srebrenica, joining more than 6,600 victims who are already reburied there.
