In May 2014, BiH was severely affected by the worst Balkan flood in over a century. Almost one third of Bosnia is affected by floods with houses, roads and railway lines being submerged in the north eastern part of the country. One million people – approximately a quarter of the population – have been affected by the floods. Around of 70 percent of the flood-affected zones were in areas contaminated by mines. Bosnian authorities reported that the floods had moved mines, cluster munitions, and unexploded ordnance (UXO), and had damaged minefield fencing and signs. At an ammunition depot in Orašje, some 250 tons of ammunition were reported as being under water on 25 May 2014. Landmine Survivors Initiatives reported that more than 3,000 mine survivors were living in the flood-affected region.
