Are Al Qaeda and the Sunni insurgents in Iraq at odds?

A report the other day claiming that Abu Ayyub al-Masri, Al Qaeda's leader in Iraq, had been killed by rivals, suggested tensions between Al Qaeda and homegrown Sunni insurgents. Also known as Abu Hamza al-Muhajir, Al-Masri (which simply means 'the Egyptian') declared an Islamic State of Iraq in the west of the country early this year. This article and this one from Conflicts Forum provide more interesting detail on the split between the Sunni groups inside Iraq.

Even if the report is accurate, it does not give much cause for celebration. The insurgents say that their differences have not undermined their determination to expel foreign forces from the country, and in any case, the extent to which some sort of central Al Qaeda operation really determines the insurgents' strategy inside Iraq was questioned by the publication of this letter to a previous Al Qaeda leader Abu Musab al-Zarqawi, late in 2005. Rather, it seems the Al Qaeda banner is one adopted locally by a particular insurgent faction to give itself greater credibility.
