At least 30 people, including several children, were killed when a fire ripped through a home that doubled as a matchstick factory in Indonesia today.

The head of North Sumatra’s disaster agency Riadil Lubis told Media that the exact cause of the fire is still unclear.

Irwan Syahri of the local disaster mitigation agency in Langkap district said the dead included three children. He said many of the victims are burned beyond recognition.

Deadly fires are not uncommon in Indonesia due to poor safety standards that are routinely flouted.

In 2017, at least 46 people were killed and dozens more injured in a blaze that tore through a fireworks factory outside Jakarta.

Seventeen people were killed when a fire ripped through a karaoke bar on Sulawesi island in 2015 and, in 2009, a fire killed 20 people at a karaoke bar in Medan, on Sumatra island.
