Open calls for attacks on Sunnis?

In a post from last night, DHinMI at Daily Kos points to a report from the McClatchy wire service that al Sadr's followers have taken over a radio station in Baghdad and are openly calling for attacks on Sunni leaders and Sunni neighborhoods:

Followers of the militant Shiite cleric Muqtada al-Sadr took over state-run television Saturday to denounce the Iraqi government, label Sunnis "terrorists" and issue what appeared to many viewers as a call to arms.

The two-hour broadcast from a community gathering in the heart of the Shiite militia stronghold of Sadr City included three members of al-Sadr's parliamentary bloc, who took questions from outraged residents demanding revenge for a series of car bombings that killed some 200 people Thursday.

I've looked around this morning, and I can't find anything about this in any of the usual places. Was it just plain wrong? Has the station been retaken? Or, is the press asleep at the switch?

Given the holiday weekend, I'm guessing it's the latter, but who knows.

If it's true, it certainly seems too important to ignore.
