Peureulak, Indonesia - The death toll from an oil well explosion in Indonesia has climbed to 21, with dozens of others in hospital, authorities said Thursday, as they extinguished the towering blaze.
The latest toll was more than double an initial count of 10 as more victims succumbed to their injuries in hospital following the accident early Wednesday morning.
An oil spill sparked a huge fire that shot up some 70 metres (230 feet) in the air, above homes and palm trees in a residential area on Sumatra island's Aceh province.
Several houses were also destroyed in the explosion in the village of Peureulak until authorities finally managed to snuff out the blaze.
"The fire has been extinguished now.... We are still monitoring the injured and the situation at the accident," said Henny Nurmayani, an official at Aceh's disaster mitigation agency.
Three dozen victims remain in hospital, she added.
The victims were collecting oil from around the entrance of the illegal old well bore when the fire erupted, police said.
Authorities are still investigating the accident, but suggested a lit cigarette as a possible cause.
"There were many people there who were smoking," national police spokesman Setyo Wasisto said earlier.
"It's a village, so many were scrambling to get oil and it was crowded." East Aceh is dotted with numerous small-scale oil drilling operations, which are often run illegally by local villagers.
There are reportedly tens of thousands of such wells across the Indonesian archipelago.
Abandoned oil wells are sometimes re-tapped while locals also drill into fresh sites to find new sources.
Deadly fires are not uncommon in Indonesia, a sprawling country of more than 260 million people where safety regulations are often flouted.
In October 47 people died after a blaze tore through a fireworks factory outside Jakarta.
