WASHINGTON (AP) — The International Monetary Fund says financially-strapped European countries must put in place bold changes to resolve a prolonged debt crisis.

The 188-nation lending agency has just received an infusion of $430 billion and is pledging to use the new money responsibly to reassure financial markets of its ability to deal with the debt problems.

That crisis has forced three European nations to seek IMF aid and is threatening to engulf Spain and other larger countries.

The IMF is wrapping up weekend meetings in Washington.
