The obvious disarray among Sunni Arab insurgents and bin Laden's group, both of which are under serious U.S. military pressure, and an uprising among Sunni tribesmen, are troubling Bin Laden.
The insurgents seem incapable of uniting under one banner.
Bin Laden employed the word "ta'assub" — "fanaticism" — to chastise insurgents.
Analysts are still studying this latest released tape but first reports seem to suggest that the tape is authentic.
Bin Laden warned the disunited "against hypocritical enemies who are infiltrating your ranks to create sedition among mujahedeen groups."
Anthony Cordesman, an analyst for Strategic and International Studies, stated bin Laden's message appeared to be note "that al-Qaida needs to be less arrogant and moderate its conduct."
Al-Qaida's attempts to impose Taliban-like Islamic laws in controlled areas as well as its killings of rival tribal figures alienated Sunni Arabs and led them to join a movement opposing al-Qaida.
U.S. troops, led by Major Lee Peters, a military spokesman, said a celebration is planned to include at least 200 Sunni sheiks and hundreds of other dignitaries to commemorate Sheik Abdul-Sattar Abu Risha, the founder of the anti-al-Qaida group who was assassinated by a bomb September 13.
The sheik's brother stated: "The people felt weak and afraid because of al-Qaida. Now there is a feeling of strength," Sheik Ahmed Abu Risha told The Associated Press. He continued: "This year I want to have a good parade to show that we support the law."
