Thermobaric and fuel-air explosives have been used in guerrilla warfare since the 1983 Beirut barracks bombing in Lebanon , which used a gas-enhanced explosive mechanism , probably propane , butane or acetylene . The explosive used by the bombers in the 1993 World Trade Center bombing in the US incorporated the FAE principle , using three tanks of bottled hydrogen gas to enhance the blast . Jemaah Islamiyah bombers used a shock-dispersed solid fuel charge , based on the thermobaric principle , to attack the Sari nightclub in the 2002 Bali bombings
