Islamic grouping claims China bombings

Image via WikipediaNot yet reported by the Chinese media, so the claims might be correct: An islamic grouping has claimed the bombings in both Shanghai and Kunming, also a few others that have not made it to my radar screen.
Here is the Reuters report about the claims, quoting a US organizations I did not know, and below you find the video clip containing the claim.

"Despite the Turkistan Islamic Party's repeated warnings to China and international community about stopping the 29th Olympics in Beijing, the Chinese have haughtily ignored our warnings," IntelCenter quoted Seyfullah as saying.

"The Turkistan Islamic Party volunteers who had gone through special preparations have started urgent actions."

Update: Global Voices points at a warning that we should not confuse the "Turkistan Islamic Party" with the more official East Turkistan Islamic Movement (well, not official of course from a Chinese perspective).
