The European Union Council President Donald Tusk told European lawmakers on Tuesday that up to 3 million more refugees could flee the fighting in Syria.

The new wave of refugees could worsen the humanitarian crisis that has strained relations between European Union (EU) members and put additional pressure on European border facilities. Currently, 2 million Syrian refugees are in Turkey.

“Today millions of potential refugees and migrants are dreaming about Europe,” Tusk said. He then went on to slam countries that have not honored the EU’s asylum rules.

The EU has currently offered new incentives to Turkey in order to better handle the Syrian refugee crisis. This offer includes up to 1 billion euros, additional EU funding to build six reception centers for refugees in Turkey, better intelligence sharing, and easing of visa restrictions.

“I know that this is a very dramatic dilemma,” Tusk said. “We have to try to cooperate with Turkey because in fact we have no other options.”

Last month, the EU agreed on plans to relocate 120,000 refugees over the next two years.

The International Organization for Migration says it has no reports of more people leaving Syria at this time. They add that Tusk’s statements on the situation are “speculative.”
