Several thousand people on July 8 began an annual 100-kilometer march to commemorate the victims of the 1995 Srebrenica massacre.

Participants in the three-day march are tracing the path taken by Bosnian Muslim men and boys fleeing Bosnian Serb forces who were advancing toward the United Nations protected area at Srebrenica on July 11, 1995.

But the commemorative march is heading in the opposite direction -- starting from Nezuk near the eastern town of Tuzla and moving toward Srebrenica.

They are due to arrive at a Srebrenica memorial center in Potocari on July 11 for a 20th anniversary commemoration of the massacre.

As many as 15,000 Muslim men and boys tried in 1995 to escape on foot through the forests to Muslim-controlled territory in eastern Bosnia-Herzegovina.

The UN Security Council pushed a vote back until July 8 on a British-drafted resolution that recognizes the Srebrenica massacre as genocide after Russian threatened to veto the draft text.
