"The downgrade means Moody's has followed its counterpart Standard & Poor's in giving Greece the lowest rating of any country it rates in the world, falling below Cuba and Ecuador."

"Austerity measures demanded by Greece's European partners and the International Monetary Fund remain highly unpopular among many of the country's voters, and face continuing street protests."
