Poland cannot afford to accept economic migrants, but it is the central Europe biggest economy's duty to accept refugees who escape wars, Polish Prime Minister Ewa Kopacz said on Thursday.

"Accepting migrants escaping to save their lives is our duty," she told news briefing during the economic forum in Southern city of Krynica Zdroj.

She also said that Poland should share the responsibility for refugees with the rest of Europe, as it may face more refugees from Ukraine, if the conflict in Donbas intensifies.
