An al-Qaida front group warned it will hunt down and kill Sunni Arab tribal leaders who cooperate with the U.S. and its Iraqi partners, saying the assassination of the leader of the revolt against the terror movement was just a beginning.

In a separate statement, the Islamic State of Iraq announced a new offensive in Ramadan, the Islamic holy month of fasting that began this week. The statement said the offensive was in honor of Abu Musab al-Zarqawi, the founder of al-Qaida in Iraq who was killed by a U.S. airstrike in June 2006.

...In a second statement posted Saturday, the purported head of the Islamic State, Abu Omar al-Baghdadi, said he was "honored to announce" the new offensive in memory of al-Zarqawi.

"Today we witness the fallacy of the Western civilization and the renaissance of the Islamic giant," al-Baghdadi said in a half-hour audio file.
