The Quran forbids suicide in any shape or form(this is explicitly stated in the Quran), hence suicide bombings are also not permitted. Another reason suicide bombings are not permitted in the Quran is because in a state of war, distinction between enemy combatants and civilians must be made. If you extrapolate then nuclear weapons are most definitely "Heram" or not kosher. The people who blow themselves up are misguided people and will end up in hell (according to the Quran). Suicide bombings are political not religious tools. Just stating the facts.
