What have the al Qa Qaa RDX and HMX been used for so far?
The BBC notes that “HMX and RDX [are] key components in plastic explosives, which have been widely used in car bombings in Iraq.”
Then there was this terrorist arms cache discovered in Riyadh, Saudi Arabia after the housing complex bombing in Riyadh. It contained “38.4 tons of ‘RDX explosive materials'”.
No word yet on the explosives used in the car bombing today near the Australian Embassy in central Baghdad.
