Several thousand people on Wednesday began an annual 100-kilometer march to commemorate the victims of the Sebrenica massacre, three days ahead of the 20th anniversary of the killings. Participants in the so called “peace march” are tracing the part taken by Bosnian Muslim men and boys fleeing Bosnian Serbs forces who were advancing towards the eastern town. Some 10,000 to 15,000 Muslim males tried to escape on foot through the forest to Muslim-controlled territory. The flight began hours before the arrival of the Bosnian Serbs at the then UN-protected area on July 11,1995. At the head of the column were some 3,000-4,000 armed men, while the rest were unarmed civilians. Almost 8,000 were captured and systematically killed in the days following the fall of Sebrenica. The lucky ones reached Muslim-held territory five days after they left. The three day March, that kicked off on Wednesday along the 105-kilometer path, is heading in the opposite direction, from Nezuk to Sebrenica. The marchers are due to arrive at a Sebrenica memorial center in Potocari on Saturday, for a commemoration of the massacres’s 20th anniversary. Bosnia’s 1992-1995 war between its Croatia, Muslims and Serbs claimed some 100,000 lives.
