The flooding was not limited to Bosnia. In neighboring Montenegro, a road was washed out, cutting off the town of Komarnica.
Water levels are also rising in some rivers in Croatia, and the Zagreb government said parts of the city of Karlovac were at risk of flooding near the river Kupa.
Most of central Europe was hit by flooding last month, with Poland, the Czech Republic and Romania being the worst hit.
Scientists from the World Weather Attribution (WWA) group said the four-day period was the wettest ever recorded in the region. They said climate change has made flooding much more severe.
Europe is the continent that is warming the fastest. According to the Copernicus climate service, the past five years have been an average of 2.3 degrees C warmer than the late 19th century.
