A pipe through which negotiators communicated with Jimmy Lee Dykes who held a five-year old boy hostage in an underground bunker in Alabama, US, is shown in this handout photo released by the Federal Bureau of Investigation on February 5. The nearly weeklong standoff ended with Dykes' death and the safe recovery of the kindergarten student, known only as Ethan. FBI used a hidden camera to watch the man and moved in to rescue the child after the suspect was seen wielding a gun and looking agitated. Reuters/FBI/handout
