Excitement at the prospect of free fuel has turned to horror and grief as a tanker exploded in flames in Pakistan.
People rushed to collect fuel from the overturned vehicle on the outskirts of the city of Bahawalpur in the country's east.
A provincial government spokesman says the tanker lost control when it blew a tyre, skidding off the road at a sharp bend along a highway.
Without warning, 45 minutes later, it exploded.
This witness says everyone nearby was engulfed by the flames.
"Children were bringing buckets to take petrol. There was a huge crowd and suddenly there was an enormous explosion."
A number of children are among the dead.
Pictures show piles of burnt-out motorcycles, apparently belonging to people who had gathered at the scene.
Many bodies are said to be burnt beyond recognition.
The tanker's driver is believed to have survived the accident, and has been taken into police custody.
These men say police tried to get people to move away from the scene, but few listened.
"The oil tanker capsized, people shouted 'Oil! Oil!' The local traffic police asked people to leave, warning it may explode, then suddenly there was fire."
"I had already taken some petrol. I was about to fill another can, but felt dizzy due to the fumes, so decided not to go back for more."
"Many people gathered here. We told them to leave the spot as there might be an explosion. People from our village came here, amongst them was the son of my cousin. My cousin came here to search for his son, but neither of them returned."
A lack of doctors or burn treatment facilities at neaby hospitals meant some of those injured had to taken to a military hospital and facilities in other cities.
Pakistan's Prime Minister, Nawaz Sharif, currently travelling overseas, has expressed his sadness at the tragedy.
Army Major-General Amjad Khattak says victims are getting the best help possible.
"Pakistan aviation helicopters have arrived. All those who are critically injured are being shifted from Bahawalpur to Multan and Kharian burns centre."
Fuel is a valued resource in Pakistan, where, according to a World Bank survey, more than 60 per cent of the population lives on less than AU$4 a day.
The accident came just before Pakistan is due to celebrate the Eid al-Fitr festival, when many families celebrate the end of Ramadan together.
