DUBAI (Reuters) - Osama bin Laden is in good health and reports about his sickness are false, al Qaeda's second-in-command Ayman al-Zawahri said in remarks posted on the Internet on Wednesday.

"Sheikh Osama bin Laden is in good health," said the militant leader in response to questions posted on the Internet. "The ill-intentioned always try to circulate false reports about him being sick."

Bin Laden and Zawahri are believed to be hiding in Afghanistan or Pakistan.
