Italy’s Emilia-Romagna region sees three rivers overflow after Boris wreaks havoc across Central and Eastern Europe.

Polish Finance Minister Andrzej Domanski said on Friday a pledge worth 5 billion euros ($5.6 billion) from the European Union to help the country cope with the fallout from its worst flooding in at least two decades may not be enough to cover its losses.

The leaders of four countries hit by Storm Boris will meet Thursday in Poland with European Commission President Ursula von der Leyen to discuss aid for the flood-hit region. The death toll from the storm which has hit central and eastern Europe in recent days rose to 24 on Wednesday and some areas are still under threat from rising waters.
