Wanted: Mad Scientist

I know this is serious but these folks and these clandestine video tapes are starting to make me laugh. Is he for real?

Al-Qaida in Iraq's leader, in a chilling audiotape released Thursday, called for nuclear scientists to join his group's holy war and urged insurgents to kidnap Westerners so they could be traded for a blind Egyptian sheik who is serving a life sentence in a U.S. prison.

The fugitive terror chief said experts in the fields of "chemistry, physics, electronics, media and all other sciences - especially nuclear scientists and explosives experts" should join his group's jihad, or holy war, against the West.

"We are in dire need of you," said the speaker, who identified himself as Abu Hamza al-Muhajir - also known as Abu Ayyub al-Masri. "The field of jihad can satisfy your scientific ambitions, and the large American bases (in Iraq) are good places to test your unconventional weapons, whether biological or dirty, as they call them."

The 20-minute audio was posted to a Web site that frequently airs al-Qaida messages. The voice could not be independently identified, but it was thought to be al-Masri's. He is believed to have succeeded Abu Musab al-Zarqawi, who died in a U.S. airstrike north of Baghdad in June, as head of the al-Qaida-linked organization.
