Greek Prime Minister Alexis Tsipras said Wednesday all sides must prevent division in Europe as they try to hammer out a solution to his country's crippling debt crisis, just days away from a final deadline.

"This is a European problem which requires a European solution... let us not allow it to become a divided Europe," Tsipras told the European Parliament, after EU leaders set a Sunday deadline for a deal on new bailout funding crucial to keeping Greece in the eurozone.
