The head of the International Monetary Fund said the world economy was in danger and urged Europeans to speak with one voice on a debt crisis that has rattled the global financial system.
In Nigeria last week, IMF Christine Lagarde said the IMF's 4 percent growth forecast for the world economy in 2012 could be revised downward, but gave no new figure.
"The world economy is in a dangerous situation," she told France's Journal du Dimanche in an interview published on Sunday.
The debt crisis, which continues into 2012 after a European Union summit on December 9 only temporarily calmed markets, "is a crisis of confidence in public debt and in the solidity of the financial system," she said.
