An audio recording posted on the Internet Wednesday, says Muslim religious scholars or Ulemas have betrayed Islamic fighters by keeping silent about U.S. actions in Iraq and Afghanistan.

The message charges the Ulemas have quit supporting the mujahedin, betraying them in the darkest circumstances and leaving them to confront the world's greatest power alone.

The recording was attributed to wanted al-Qaida-linked terrorist Abu Musab al-Zarqwai. Its authenticity could not be independently verified.

Al-Zarqawi - Iraq's most wanted man - is believed to have fled his base in Fallujah during the U.S.-led assault on the insurgent-held city earlier this month.
