"It is legal for someone as young as 12 to request and receive euthanasia, as long as the parents give their permission, according to Dutch law."

"For those 16 to 18, parents must be aware of the request but their permission is not necessary....  [Steven] Pleiter, the director of the end-of-life clinic in The Hague, said that gaining approval for euthanasia was a complex process. After the clinic receives a request, he said, it is reviewed, with doctors and nurses making home visits and conducting multiple interviews. Every person seeking euthanasia must meet criteria set by Dutch law, which include ensuring that the request is voluntary, that the person is in unbearable suffering with a poor prognosis that shows no improvement, and that he or she is mentally able to understand the process and its consequences.... The clinic received 2,600 euthanasia requests in 2018 — 27 percent to 28 percent of them were from mentally ill patients, according to Mr. Pleiter. Of the 727 patients who were euthanized last year, about 50 were patients with mental health problems, he said."

From "Dutch Teenager’s Death Sets Off Debate, and Media Corrections" (NYT). The teenager, Noa Pothoven, was not, contrary to news reports, given this Dutch euthanasia. She asked for it but was denied for reasons that are not disclosed. She died, we're now told, by her own action of ceasing to eat or drink. It sounds as though she was with her family and under medical care when she died but no lethal injection was delivered by a doctor. Her mother is quoted as having said, before the death, "Noa doesn’t want this life anymore. She just longs for peace."

ADDED: A few important details from the BBC report:

1. The "friends and family want people to know that she did not die of euthanasia" and want their privacy respected. I presume they are not happy about the criticism they received after the way the story was originally told.

2. After Noa Pothoven stopped eating, she was force fed through a tube for a while, but "[e]ventually her family accepted her wish to die, so they stopped forcing her to stay alive and instead used palliative care to make her final days as peaceful and bearable as possible." There seems to have been "palliative sedation... to alleviate suffering" as she died. This is easy to confuse with euthanasia, but it's not the same as the euthanasia procedure described above.

3. The girl's own refusal to eat is considered the cause of death. The use "palliative drugs" to ease a path to death when force-feeding is still a way back to life could be characterized as euthanasia, but it's not that official process defined in Dutch law. The Royal Dutch Medical Association is anxious to communicate this distinction: "Under Dutch law, euthanasia is defined as the active termination of life, by a physician, at a patients voluntary and well informed request... on persons who suffer unbearably from a medical condition." Accepting that a person is committing suicide and not actively intervening to save her is not euthanasia as defined in Dutch law, even if drugs are given to ease the pain.

4. The parents blame the Dutch authorities for making her wait "more than a year" to get treatment for her eating disorder. When she finally got treatment, it was intense — including an induced coma with tube feeding. The BBC article does not go into the difference that might have been made if she had received treatment for anorexia much earlier or the psychological effect of forcing a tube into a person who was traumatized by rape.
