LONDON (AP) — The parents of a critically ill infant are returning to court for the latest stage in their effort to seek permission to take the child to the United States for medical treatment.

Britain's High Court is considering new evidence in the case of Charlie Gard. The 11-month-old has a rare genetic condition, and his parents want to take him to America to receive an experimental treatment.

Doctors say that the treatment won't help and could cause the child pain.

The judge has scheduled a two-day hearing to consider fresh evidence, after the doctor who was to conduct the treatment came to London to evaluate the child.

Last week Great Ormond Street Hospital told the parents that a report on the latest scan of Charlie's brain made for "sad reading."
