At least 59 houses in the Croatian municipality of Gracac, in the southern Lika region, were flooded over the past two days, mayor Robert Juko told the Croatian state news agency Hina, adding that local residents were evacuated in time and are safe.

Heavy rain in recent days caused some rivers to overflow their banks, flooding homes, roads and public buildings in Gracac and several other towns in the region.

Classes in the town of Obrovac, northern Dalmatia, were cancelled after water got into the schools there. Parts of the town were left without electricity.

Authorities in Hrvatska Kostajnica, a town on the border with Bosnia, declared an emergency after the Una River rose dramatically overnight.

Prime Minister Andrej Plenkovic said his government would provide all necessary funding and aid.

Interior Minister Davor Bozinovic, Veterans Minister Tomo Medved, and Defence Minister Mario Banozic will visit the flooded areas later today.
