Some 200,000 people were killed and 1.8 million driven from their homes during the 1992-95 conflict.
Marko Jurisic, from the International Red Cross working group on missing persons, said today that UN and local forensic experts so far have exhumed 16,500 bodies from about 580 gravesites.
He added that at least 8,000 of those listed as missing are probably in dozens of mass graves throughout the country that have not yet been excavated. Six thousand others cannot be accounted for.
Jurisic said forensic experts do not have relevant information on graves, and he called for a unified list of those who are missing and those who have been found and identified.
Bosnia's Serbian entity and its Muslim-Croat federation have separate missing-persons commissions. A newly founded central Missing Persons Institute is soon expected to take over the work of both commissions and search for the missing regardless of their ethnicity.
