"In the face of a major challenge, Europe can't just say: we will not deal with this. That would completely wrong," said German Chancellor Angela Merkel. "We have to find answers together."

European Union leaders, faced with a staggering migration crisis and deep divisions over how to tackle it, managed to agree early Thursday to boost border controls to ease the influx and to send 1 billion euros ($1.1 billion) to international agencies helping refugees at camps near their home countries.

The leaders also pledged to boost support to Lebanon, Turkey and Jordan to help them cope with the millions fleeing the fighting in Syria.

Summy Co. from the song's writers, only covered specific piano arrangements of the song and not its lyrics.
