Federal Reserve Chairman Ben Bernanke said on Monday he was convinced Europe was committed to addressing its debt troubles to keep the European Union together.

European leadership is strongly committed to doing whatever is necessary to preserve the euro, preserve the euro zone, Bernanke said in remarks at the Woodrow Wilson Center in Washington.

When asked whether Europe had raised enough money to stabilize the region, Bernanke said the amount covered the obligations of Greece, Portugal and Spain for a number of years but acknowledged that more may be necessary.
