The 2004 Nosratabad fuel tanker explosion was a catastrophic incident that took place on 24 June 2004, near Iran's border with Afghanistan, resulting in at least 90 fatalities and 114 injuries.

The disaster occurred when a petrol truck lost control and collided with a bus at the Nosratabad police checkpoint, located about 110 kilometres (68 mi) west of Zahedan.

The checkpoint at Nosratabad was situated on a sharp bend and was known for creating long queues of buses and cars, and its location and outdated inspection methods would later be criticised by Zahedan parliamentarian Hossein Ali Shahriari.

[3] Earlier in the year on 18 February 2004, a train carrying sulphur, fertiliser, petrol, and cotton wool derailed, separated, and exploded near Nishapur, killing almost 300 people.

[5][6][2] The impact caused the truck to explode, creating a fireball that engulfed five other buses and several additional vehicles that were stopped at the checkpoint, some of which were carrying tar, further exacerbating the flames.
