The below is a quote from Joby Warrick's book "Black Flags: The Rise of ISIS":

Their efforts at jihad in Jordan had been anything but glorious. The leaders of Maqdisi’s small band had been arrested before they could carry out their first operation, a planned attack on an Israeli border post. The other groups’ targets had consisted of small-time symbols of Western corruption, from liquor stores to video shops and pornographic movie houses. One of the early attempts at a bombing had been a spectacular failure: A member of the group had volunteered to plant explosives inside a local adult cinema called the Salwa. After a few minutes in the theater, the would-be assailant had become so engrossed in the film that he forgot about his bomb. As he sat, glued to the screen, the device detonated under his feet. No patrons were hurt, but the bomber lost both his legs. Six years later, the double-amputee was among Sabha’s charges at al-Jafr Prison. The doctor had noticed him on his first visit, propped up on his bunk, his pant legs neatly pinned at the knee.
