Ah, that would be ammonium nitrate...
This is a fairly important point; you'd think the writer could have gotten at least this much right.
Yes, you're right. Pretty bad mistake on the writer's part. Add that he is the only one reporting that Cheema was a "Palestinian" and it starts making him look pretty unreliable as a source in this case.
And he could have looked up what TATP is. If he had, or the AP reporter who wrote the story based on what the father said, had done that, he/they would have found that while TATP (TriAcetone TriPeroxide) is made from Hydrogen peroxide (not the the 3% solution used as a disinfectant!), acetone and some strong acid to catalyze the reaction, it isn't the same thing as Hydrogen Peroxide, any more than TNT is toluene, or ammonium nitrate is ammonia.
"...Hinrichs attempted to buy aluminum nitrate from a Norman feed store. Aluminum nitrate was used in the bombs at the Oklahoma City federal building..."

The reporter flunked chemistry.
