A recent discussion on a password-protected al-Qaeda affiliated forum concerned the use of propane cylinders in bombing operations, directed against myriad targets, including oil pipelines, buildings, and individuals. The member opening the inquiry proposed using the cylinders on oil pipes, and sought advice as to the advantages of such an operation. Those who replied maintain that it works well, and provides an equivalent destructive power to TNT; however, some members advocate detonating propane cylinders in car bombings, as they acknowledge the Salafist Group for Call and Combat (GSPC) had utilized them, or for attacks upon tanks, like the ?brothers in Palestine.?
One member in particular claims to have been a ?helping agent in one operation,? and describes using propane cylinders as a component in a car bombing. He also suggests ways to augment the explosions, with the use of shrapnel, benzene, or napalm, or oxygen tanks in lieu of propane, and provides a mini-manual for preparing a car bomb with just the cylinder as the explosive.
