It's official: China blames Muslims for blast

Uighurs.

Officials have suggested that the attack was part of a “holy war” orchestrated by theEast Turkestan Islamic Movement, or ETIM. (To which I say, no kidding.)

This despite the steady stream of so-called western terror analysts who "cast doubt on whether the group is strong enough to pose a serious threat" and "say such claims are highly inflated."

The Human Rights groups all have their theories too - needless to say it is accusing the Chinese government of "using such cases as a pretext for increased repression of China’s eight million Uighurs, a Turkic-speaking people who have long bridled under rule from Beijing."
