The Trump administration is demanding answers from Spain a week after 25-year-old sexual assault victim Noelia Castillo was permitted to die by euthanasia.

A leaked diplomatic cable, obtained by The Post

, shows the State Department instructed the US Embassy in Madrid Tuesday to open an investigation into the Spanish law enforcement’s handling of repeated sex attacks, including gang rapes, against Castillo leading up to her tragic death.

Top US Embassy officials were also told to convey to the Spanish government the Trump administration’s “serious concerns” with the “many systemic human rights failures” that led Castillo to seek out assisted suicide and allowed the terminal act to be performed even after she reportedly “expressed hesitancy” in her final hours.

“We are deeply concerned by allegations that Ms. Castillo was repeatedly sexually assaulted while under state care and that no perpetrators have been brought to justice,” the cable reads.

“We are also aware of reports that Ms. Castillo expressed hesitancy to undergo euthanasia in her final hours, but that these indications were ignored,” it continues. “This case raises serious concerns about the application of Spain’s euthanasia law, particularly in cases involving psychiatric conditions and non-terminal suffering.”
