AT least 10 people have been killed and dozens more injured after a fire at an illegal oil well in Indonesia’s Aceh province.

Authorities confirmed an oil spill sparked a huge blaze about 6.30pm local time (5.30am AEDT) that torched at least three houses and was still out of control mid-morning.

“The [fire] is still soaring high and has not yet successfully been extinguished,” Saiful, head of Aceh’s Ranto Peureulak subdistrict who goes by one name, said.

Aceh is a semi-autonomous Indonesian area on the northwest tip of Sumatra Island. It’s known for its beaches, diving sites and mountain wilderness areas.

It comes nearly a month after an oil spill at state-owned oil and gas firm Pertamina, in East Kalimantan, which spread across an area greater than the city of Paris and caused an out-of-control blaze that killed five fishermen.

Indonesian authorities declared a state of emergency after the spill, which has caused significant environmental and economic damage.

More to come.
