A massive floodwave moving across Central Europe is threatening new areas and raising concerns among residents and leaders.

Based on estimates from local officials, the damage to infrastructure could reach a combined $10 billion in these two countries alone. Poland's finance minister said the $5.6 billion allotted from EU funds would cover some, but not all of the costs to recover from the floods.

European Union chief Ursula von der Leyen on Thursday pledged billions of dollars 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.
