KALLUDER, Kosovo (AP) — Erblin Ademi watched from afar as workers excavated recently discovered mass graves from the 1998-99 war in Kosovo. Nearly 30 years after his father went missing, Ademi both feared and wished that his remains will finally be found. Some 1,600 people are still missing from the conflict, believed scattered in unmarked mass graves, and Ademi’s family had endured years of anguish and disappointments at failed efforts to find his father’s remains. They are now cautiously optimistic because the newly found graves are near to where Ademi was last seen. Police in Kosovo said last month they arrested two ethnic Serbs on suspicion of war crimes in connection with the mass graves, several days before the latest excavations started.
