Suicide bomb is a colloquialism for a type of terrorist attack that causes widespread death and destruction, in which the bomber dies or expects to die. While this type of attack has been used sporadically in human history, it saw widespread use in the middle 20th century and early 21st century. The scale of the attack can vary from an individual carrying a bomb upon his or her person, to something much larger, such as the September 11, 2001 attacks which saw terrorists use passenger planes to crash into targets in the United States.
