Two tiny Arabian leopard cubs are the latest addition to a zoo in war-torn Yemen where supplies are so low the animals are days away from starvation.
The lives of the adorable cubs are hanging by a thread after campaigners said food supplies at the zoo, in the city of Taiz, southern Yemen, will run out in a week.
Taiz Zoo is currently home to 26 Arabian leopards and the survival of the new cubs is paramount for the species with only 80 of the big cats still alive in the wild.
But with Yemen locked in a bloody civil war, there are fears they will soon die of starvation.
The cubs, who are yet to be named and were born to an Arabian leopard called Fedhah, are reportedly under round-the-clock guard after two previous sets of cubs born at the zoo in the last six months went missing.
Alongside the zoo's new cubs, suffering creatures include 26 adult leopards, 19 lions, hyenas, a crocodile, baboons, porcupines, monkeys and birds.
Fundraisers have raised cash to feed more than 200 animals since the attraction was declared bankrupt in 2015 due to having no visitors as a result of the war. But they fear animals could soon starve to death.
A spokesman for SOS Zoo and Bear Rescue, a volunteer group fighting to keep the animals alive, said: 'We are desperately trying to find a way to have the animals evacuated but there are many challenges.
'In the meantime, we need to raise some funds so they don't die of starvation.
'We have been keeping them alive since February but only have enough money for food and water for another week.
'With no end to the war in sight and the funds just about gone, the animals face starvation again.
'With no organisation willing to step in to help in a dangerous war zone, time is running out for the animals.
'The arrival of the cubs, which should be a cause for celebration, is marred by sadness about their uncertain future.'
Taiz Zoo first hit the headlines earlier this year when images of a leopard eating its dead mate and of animals with horrific sores trapped in inadequate conditions went viral on social media.
The human tragedy in Yemen since armed conflict began in March 2015 is estimated to have left 21.2 million people - 82 per cent of the population - requiring some form of humanitarian assistance.
And the crisis also means the abandoned zoo - home to about 280 animals in total - has become the focus of a rescue effort from SOS Zoo and Bear Rescue and local volunteers.
Campaigners hope in the long term to evacuate the animals into sanctuaries or wildlife parks in Africa or in the United Arab Emirates but say the current siege and military operations mean at present it is impossible to get the animals out.
Volunteers say the minimum amount needed per week to feed and care for the zoo's carnivores alone is approximately £2,662 but allege the local government, which previously paid to feed the herbivores, is unable to provide any financial support.
SOS Zoo and Bear Rescue say a contract was agreed with local non-governmental organisation Tamdeen Youth Foundation in March to oversee food distribution for the animals and cage cleaning but funds are running low.
Chantal Jonkergouw, founder of SOS Zoo and Bear Rescue, is now battling to obtain evacuation permits to transport the leopard cubs and other animals in the zoo to a safe home.
Chantal said: 'We are fighting for permits to evacuate the zoo, but so far we have run into various walls.
'The International Union for the Conservation of Nature says that these leopards need to be preserved for future breeding, so the Arabian leopard's population of only 80 can recover over time.'
Yemen has spent the past 18 months torn apart by civil war, with violence raging between Houthi rebel forces and pro-government supporters of Abdrabbuh Mansour Hadi, who was handed over power from long-standing authoritarian president Ali Abdulleh Saleh.
More than 6,800 people have been killed and tens of thousands injured in the fighting, which has raged since March 2015 and shows no sign of being brought to an end.
Jihadist militants from Al-Qaeda and rival affiliates of so-called-Islamic State are also reported to be taking advantage of the country's turmoil in the south.
SOS Zoo and Bear Rescue have joined forces with fellow charity A Lion's Heart to petition the general secretary of CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, for emergency permits for the animals of Taiz Zoo.
