SUMMARY BOX: EU says Greece needs $20 billion more

NEED GROWS: Greece's international debt inspectors have discovered it needs €15 billion ($20 billion) more than the €130 billion it's to receive in its second bailout and the €100 billion in debt relief it's getting from private investors.

EUROPE ON THE HOOK: The European Commission has asked the other 16 countries in the eurozone to help provide the $20 billion, indicating a limit has been reached to the internal cuts Greece can make.

BANKS, GOVERNMENTS: The gap could be filled by other euro governments, national central banks or state-owned banks.
