An American tourist and her driver have been rescued unharmed after being kidnapped in Queen Elizabeth National Park in southwestern Uganda last week, Ugandan authorities said on Sunday.

Kimberley Sue Endecott, 35, was abducted by gunmen near the border of the Democratic Republic of Congo on April 4. The kidnappers later demanded a ransom of $500,000 for her release; a safari firm said on Sunday that a ransom had been paid, though the amount was not clear.

“She has been located and rescued unharmed,” Uganda military spokesman Brigadier Richard Karemire said, referring to the tourist.
