All those "organisations" work together.
Remember the IRA? They admitted they bought bombs from extreme Islam groups.
All those terrorist groups are related. If only to buy "stuff" from eachother.
Besides... personaly I have a hard time believing the ETA itself would be so stupid...
They useally try to blow up certain ppl or locations.
This is just to much to be just ETA.
Remember the Spanish ware freind number1 when USA invaded Iraq...
