The U.S. Justice Department on Wednesday asked courts to denaturalize two Bosnian Muslims who have been convicted in their native country of carrying out an execution-style massacre of Croatian villagers during the Balkan wars. Edin Dzeko, 46, and Sammy Rasema Yetisen, 45, both alleged former members of an elite Bosnian military unit responsible for carrying out the 1993 attack that killed 22 civilians, are accused of hiding their crimes on their refugee, permanent resident and citizenship applications.
