This article provides an overview of the current fuel supply situation in the Gaza Strip. It examines how much fuel is needed for Gaza’s basic humanitarian needs, how much fuel is held by Hamas, and who is responsible for providing more fuel once it runs out. It concludes that Israel’s denial of fuel supply into Gaza offers relatively marginal tactical advantages since Hamas has enough diesel stored away to last for several months. Diesel denial mainly affects the operation of hospitals and water supply to Gaza’s population, adding to international pressure against Israel to end its military campaign.
