WARSAW, Poland -- Bosnian church leaders defended their decision to hold a Mass for civilians and former soldiers slaughtered by victorious communist forces in Yugoslavia, despite international condemnations and domestic protests. Msgr. Ivo Tomasevic, secretary-general of the Sarajevo-based bishops' conference, told Catholic News Service the Mass in Sarajevo's Sacred Heart Cathedral, led by Cardinal Vinko Puljic, marked the 75th anniversary of the massacre of mostly ethnic Croatian internees sent back to what was then Yugoslavia from a camp in Bleiburg, Austria.
