Thousands have lined Sarajevo's main street as a huge truck bearing 136 coffins passed on its way to Srebrenica, where newly identified victims of Europe's worst massacre since World War II will be buried on the 20th anniversary of the crime.

As the truck covered with a huge Bosnian flag and with hundreds of flowers tucked into the canvas rolled down the street covered with white rose petals Thursday, the sobbing of mothers, sisters and wives of the victims broke the silence.

It stopped in front of Bosnia's presidency where the weeping crowd tucked more flowers into the canvas.

On July 11, 1995, Serb troops overran the eastern Bosnian Muslim enclave of Srebrenica and executed some 8,000 Muslim men and boys. International courts labeled the crime an act of genocide.
