Bosnia-Hercegovina is marking 20 years since the start of its civil war, a conflict that saw the worst atrocities in Europe since World War II.The conflict began in April 1992 as part of the break-up of Yugoslavia.

About 100,000 people were killed and nearly half the population forced from their homes in four years of fighting. The main event is in the capital Sarajevo where 11,541 red chairs fill the road where the conflict started – one for each of the city’s victims. People have been placing white flowers on some of the chairs as they walk alongside them. A teddy bear and toys have been placed on some of the small chairs symbolising a child killed during the four-year long siege by Serb forces. Sarajevans were asked to stop what they were doing at 12:00 GMT for an hour to mark the start of the conflict.
