JOHANNESBURG, South Africa - An international organization that fights AIDS and other communicable diseases is demanding that Zimbabwe return millions of dollars in donations it says were misused.

The Global Fund to Fight AIDS, Tuberculosis and Malaria says it wants $7.3 million back from the $12.3 million it deposited into Zimbabwe's Reserve Bank last year.

It has not said how the funds were misspent.

Communications director Jon Liden says the Zimbabwean government promised to return the money by Thursday.

The fund decides Friday whether to grant Zimbabwe's request for more money.

Attempts to reach Zimbabwean government officials on Monday were not immediately successful.
