The battle for the last scrap of land held by ISIS has taken longer than expected.
Bosnia Mass Grave May Be Biggest
This site in Bosnia where forensic teams are digging could be the largest mass grave for victims of ethnic cleansing. Its existence has been known for years but not its location. Bosnia's Institute for Missing Persons says the exact spot and details of the victims were known only to local Bosnian Serb witnesses who kept silent. Suad Zeric survived detention in three military camps during the 1992-95 Bosnian war. He's been able to identify one of his missing uncles among the remains found so far at Tomasica.
