In Bosnia, more than a quarter of its 4 million people had been affected by the worst floods to hit the Balkans in living memory, comparing the "terrifying" destruction to that of the country's 1992-95 war.
Serbia has been fighting catastrophic floods since May 14, that have endangered a large number of inhabitants, damaged houses, road and energy infrastructure, and destroyed livestock and crops, primarily in the west of the country.
The regional death toll reached more than 40, after the heaviest rainfall since records began 120 years ago caused rivers to burst their banks and triggered hundreds of landslides. So far, 20 of those deaths have been recorded in Serbia.
The governments of the Federation of Bosnia-Herzegovina, and Serbia, declared May 20 was a day of mourning, for those who lost their lives in the flooding.
