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 recover from its worst flooding in at least two decades may not be enough to cover its losses.

European Union chief Ursula von der Leyen on Thursday pledged billions of euros in aid for Central European countries that suffered enormous damage to infrastructure and housing during the massive flooding that has so far claimed 24 lives in the region.

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.
