What kind of bombs did terrorists use?

Terrorists have used various types of bombs, including improvised explosive devices (IEDs), car bombs, and suicide vests. IEDs are often made from readily available materials and can be detonated remotely or by timers. Car bombs typically involve explosives placed in vehicles to target crowded areas or specific buildings. Suicide vests are worn by individuals to maximize casualties in attacks, as the bomber detonates the explosives while in close proximity to their targets.
