An oil tanker crashed on a road near Bahawalpur on Sunday and more that 153 people, many of whom had rushed to collect leaking fuel, were killed when it exploded.

The tanker carrying 40,000 litres of fuel overturned after trying to make a sharp turn while travelling from Karachi to Lahore on the main highway.

Nearly a hundred people were injured as a result of the incident, the government officials said.

A doctor at Bahawalpur’s Victoria Hospital in south Punjab said the latest deaths occurred at a hospital in Multan where some of the 50 critically injured were taken, many of them suffering extensive burns.

A senior rescue official in the area said the death toll could rise further as dozens are still in critical condition.

The disaster occurred when hundreds of residents of a nearby village gathered at the site of an overturned oil tanker to collect the leaking fuel. It’s believed that a spark from the many cars and motorcycles that raced to the scene ignited the fuel.

Dr. Mohammad Baqar, a senior rescue official in the area, confirmed the latest toll, updating a previous figure.

He says many of the bodies were burned beyond recognition and will have to be identified through DNA testing.
