Zarqawi seriously wounded?

The Times of London reportsBin Laden henchman "seriously wounded". After reading the article, I am somewhat in doubt:

The doctor told an Iraqi reporter in the western city of Ramadi that Zarqawi was bleeding heavily when he was brought into hospital on Wednesday. After treating his wounds the doctor tried to persuade him to remain, but the Jordanian-born terrorist’s minders drove him away.

The claim was supported yesterday by a senior commander in the Iraqi resistance who had been to Ramadi to investigate the report. The doctor, who refused to specify the nature of the wounds and asked not to be identified, was detained by the Americans on Friday for questioning, residents said.

What the heck is "senior commander in the Iraqi resistance" (who are they resisting - their own elected government?) and why was he "investigating" the report?
