CLEVELAND - The Cleveland Clinic said Friday that Azerbaijani President Geidar Aliev was continuing to improve.

Aliev, who arrived at the clinic Aug. 6, is being treated for congestive heart failure and kidney problems, the clinic reported.

"He is responding well to medical care and is resting comfortably," the statement said.

Aliev, 80, who has a history of heart trouble, left a Turkish hospital for treatment at the clinic.

Rumors persist that his health is too precarious to survive a presidential campaign or take on another term. .
