Sleeping in squalid conditions, queuing for hours on end for food and struggling to care for a newborn baby are just some of the horrifying challenges girls in Iran's grim prison's face.

Dozens of juvenile offenders - some of whom are just nine years old - are languishing on death row for crimes such as murder, drug trafficking and armed robbery.

In Iran, the second-biggest user of capital punishment in the world, young women can be hanged for crimes, following unfair trials, including those based on forced confessions extracted through torture and other ill-treatment.

The frightened girls are imprisoned in a Juvenile Delinquents Correction Centre after their sentence verdict and a large number of the inmates are then killed when they reach 18.

Last year there was a disturbing escalation in the use of the death penalty in Iran, with at least 830 people executed between 1 January and 1 November 2015. There were reports that at least four of these were juvenile offenders.

Award-winning photographer Sadegh Souri, who lives in Tehran, has given an insight to the harsh conditions young people face in these grimy institutions as they anticipate their fate.

Mr Souri, documentary winner at the 2015 Lens Culture visual storytelling awards, shot 17-year-old Mahsa.

She was imprisoned after killing her father with a kitchen knife in a dispute over her future husband.

Her brothers have requested the death penalty or lex-talionis - an 'eye for an eye' - for her.

Another convict is 16-year-old Nazanin. She was arrested six months ago for the possession of 621 grams of cocaine.

She is left to anxiously wait the judge's verdict.

Meanwhile, Shaqayeq, 15, has been imprisoned for almost a year on charge of armed robbery from a chain store in Tehran.

Although she carried out the crime with her boyfriend, he managed to escape from the police leaving her to take the blame alone.

Shaqayeq's grandmother visited her 12 months after she was sent to the facility.

Her death sentence has been issued and she must reach 18 before the verdict can be carried out.

One of the most heart-wrenching images is that of 17-year-old Zahra and her newborn baby.

Female inmates can keep their babies with them in the prison until they are two years old.

Zahra, who married at 14 and has two children, is in jail for stealing women's mobile phones. She has been in prison for the same reason three times.

Mr Souri's pictures also show the more mundane aspects of life in the correction centres.

In the black and white photographs the inmates are pictured waiting in line for hours on end for food, in the yard where they are allowed to spend just two hours outside a day and praying.

After prayers, he talks about the correct upbringing methods for the girls and prays to God to forgive them.

Another inmate is 16-year-old Sowgand. While she was home alone, officers entered her house with a search warrant and found 250kg of opium, 30g of cocaine and 20g of heroin.

The narcotics belonged to her father, but as only Sowgand had been at home at the time, she was arrested and detained.

It is almost one year on and none of her family members have visited her.

To save herself the 13-year-old wounded her arm with a knife.

Dozens of juvenile offenders are languishing on death row in Iran, a damning new report by Amnesty International has revealed - despite Iran's claims to have 'reformed' the way it deals with alleged capital crimes by under-18s.

In 2014 Iran is believed to have carried out the highest number of executions anywhere in the world except for China. The Iranian authorities or state-controlled or state-sanctioned media officially announced 289 executions (278 men and 11 women), though reliable sources reported at least 454 more executions in addition to those officially announced, bringing the total number of executions in 2014 to at least 743.

Of those officially announced, 122 involved individuals convicted of drug-related offences and 29 were carried out in public.

The vast majority of executions in Iran are for crimes such as drug-related offences where international law clearly prohibits the death penalty as the offences are not 'the most serious crimes'.

Amnesty International Middle East Deputy Director Said Boumedouha said: 'The report sheds light on Iran's shameful disregard for the rights of children. Iran is one of the few countries that continues to execute juvenile offenders in blatant violation of the absolute legal prohibition on the use of the death penalty against people under the age of 18 years at the time of the crime.

'The report paints a deeply distressing picture of juvenile offenders languishing on death row, robbed of valuable years of their lives - often after being sentenced to death following unfair trials, including those based on forced confessions extracted through torture and other ill-treatment.

'Despite some juvenile justice reforms, Iran continues to lag behind the rest of the world, maintaining laws that permit girls as young as nine and boys as young as 15 to be sentenced to death.

'Instead of introducing half-hearted reforms that fall woefully short, Iran's authorities must accept that what they really need to do is commute the death sentences of all juvenile offenders, and end the use of the death penalty against juvenile offenders in Iran once and for all.'

Journalist Mr Souri was born in 1985 in Nahavand City, Hamedan Province in Iran.

He has a BA in Photography and Cinematography from the University of Applied Science and Technology.
