The WP ran an article about an emgagement outside Ramadi back in mid-August in which US forces discovered and beat back an estimated 70 AQI folks (with maybe 50% casualties to the AQI force) whose ostensible target was this sheik. I think it was called the Battle of Turtle Island but my memory may well be defective as to the island's name. The subsequent death of the sheik may make a point about the tenacity and dedication of the opposition, especially because Abdul Sattar assuredly had pretty significant protection in place. Alternatively, one might instead choose to accept that it was an inside job committed by one of his supposed allies--shades of Mario Puzo's Godfather.
