AlQa'dah 19, 1436, Sep 3, 2015, SPA -- Polish Foreign Minister Grzegorz Schetyna said on Thursday that Europe should do all it can to stop illegal migrants from entering, though the country is prepared to share the burden of giving shelter to refugees in genuine need, Reuters reported. "All must be done to stop immigration at Europe's borders. We have to defend ourselves against illegal, uncontrolled immigration," Schetyna told public broadcaster TVP1. The European Union is struggling to cope with its biggest influx of refugees since World War Two, most fleeing war or extreme poverty in Africa and the Middle East.
