A witness told a Belgrade court that alleged paramilitary Dragana Djekic was with her on the day in February 1993 when 20 people were abducted from a passenger train in Strpci in Bosnia and then killed.
A witness at the trial in Belgrade of two former Bosnian Serb soldiers accused of participating in killing 27 Bosniak civilians in 1992 said that that his previous testimony incriminating the defendants was false.
Mile Vujevic, Vukasin Draskovic, Gojko Stevanovic and Ljiljan Mitrovic were convicted of committing a crime against humanity for their involvement in killing 67 fleeing Bosniak civilians in Lokanj, near Zvornik, in 1992.
