Nour is raising her four-month-old daughter in Lebanon's most overpopulated women's prison, struggling to get formula and nappies for her baby as the country's economy lies in tatters.

"I don't have enough milk to breastfeed, and baby formula isn't readily available," said the 25-year-old, who was detained eight months ago on drug-related accusations.

"Sometimes my daughter doesn't have formula for three days," she added, as green-eyed Amar wriggled on her lap.

Lebanese authorities have long struggled to care for the more than 8,000 people stuck in the country's jails.

But three years of an unprecedented economic crisis mean even basics like medicines are lacking, while cash-strapped families struggle to support their jailed relatives.

Essentials like baby formula have become luxuries for many Lebanese, as the financial collapse -- dubbed by the World Bank as one of the worst in recent world history -- has pushed most of the population into poverty.

A months-long judges' strike has exacerbated the situation in prisons, contributing to overcrowding.

Nour said she and her daughter shared a cell at the Baabda women's prison with another 23 people, including two other babies.

She said she sometimes kept Amar in the same nappy overnight while waiting for her parents to bring fresh supplies, but said even they can "barely help with one percent of my baby's needs".

In a hushed voice, she said the shower water gave her and her daughter rashes, but that Amar had never been examined by a prison doctor.

"We all make mistakes, but the punishment we get here is double," Nour said.

'We need basics'

Inmates at the prison, located outside the capital Beirut, spoke to AFP in the presence of the prison director and declined to provide their surnames.

Around them, in the facility's breakroom, paint peeled off the walls and water dripped from the ceiling.

Rampant inflation and higher fuel prices have also prevented families from visiting their jailed relatives regularly.

Bushra, another inmate, said she had not seen her teenage daughter for nine months because her family could not afford transportation.

She was detained earlier this year on slander allegations and has been in jail ever since.

"I miss my daughter," said the tattooed 28-year-old, as her eyes welled up with tears.

"So many mothers here cannot even see their children," she added.

Interior Minister Bassam Mawlawi said in September that Lebanon's economic crisis had "multiplied the suffering of inmates".

His ministry has appealed for more international support for the prison system, citing overcrowding, poor maintenance and shortages of food and medications.

Inmate Tatiana, 32, expressed helplessness at her and her family's situation. She said her mother had slipped into poverty and was living on just $1 a day.

Prisoners "need basics: shampoo, deodorant, clothes," said Tatiana, who has been waiting for a court hearing for nearly three years.

"But our parents cannot afford them for themselves, how can they buy those things for us?" she added, dark circles lining her eyes.

'Absent state'

Tatiana is among the nearly 80 percent of Lebanon's prison population languishing in pre-trial detention, according to interior ministry figures. Prison occupancy stands at 323 percent nationwide.

The country's already slow judiciary has been paralysed since August, when judges started an open-ended strike to demand better wages.

Inmates told AFP they slept on dirty mattresses strewn on the floor in a one-toilet cell shared between more than 20 people.

Baabda women's prison director Nancy Ibrahim said more than 105 detainees were crammed into the jail's five cells, compared to around 80 before the economic collapse.

Non-governmental organisations help with everything from food to "medications, vaccinations for the children" and maintenance, she told AFP from her office at the facility.

Rana Younes, 25, a social worker at Dar Al Amal, said her organisation helps women prisoners get the basics including sanitary pads, and also provides legal assistance and even funding for cancer treatments.

She said prisoners sometimes missed court hearings because authorities failed to secure fuel or transportation for them.

Dar Al Amal has spent thousands of dollars on repairs for worn-out pipes and trucked-in water supplies at the Baabda prison, said organisation director Hoda Kara.

"Parents can no longer help, the state is absent, so we try to fill the gap," she said.
