Hundreds children are being held in an Egyptian prison without access to clean water, sunlight or medical care, according to a human rights organisation.

El Nadeem Centre for Rehabilitation of Victims of Violence claims that around 600 boys, aged between 14 and 17, are being held at a detention centre in Banha, north of Cairo.

Halim Heneish, a lawyer for the Egyptian organisation, has met with the parents of some of the imprisoned boys and claimed that the boys had been kept in darkened cells and prevented from accessing legal or medical aid.

“It’s not legal to keep them there. According to Egyptian law, minors should be kept in juvenile detention,” Mr Heneish told The Times.

According to the El Nadeem’s report, many of the boys have been denied medical attention.

Mostafa Osama Mohie El-Din, 17, who was shot in the eye, has been detained since September. Another 17-year-old boy, Ahmed Sayed Youssef, has been imprisoned in the same facility since February – and according to the Centre’s information is suffering from a broken leg.

Islma Salah, also 17, has been imprisoned since August – and his mother told Egyptian media outlet Mada Masr her son has undergone torture since being arrested.

Radwan Ahmed, the father of a 14-year-old boy detained by police in September, told The Times that his son was living with 25 others in a single room at the camp.

“Dozens of policemen raided our home at 2am and took my son. They beat him and electrocuted him for several days,” he said.

“I only get to see him when they move the boys from the police trucks to the courtroom for their detention renewal sessions, but we can’t properly talk
