Khartoum: After shocking images showing a group of starving and malnourished lions in Sudan surfaced online, an online campaign has been started to save them. Unfortunately, one of the five lions who was held in cages at Khartoum’s Al-Qureshi Park already died on Monday, after suffering from shortages of food and medicine.

In a Facebook post, activist Osman Salih posted images of the lion on Saturday, and wrote,”seeing these animals caged and be treated this way made my blood boil.”

“I regret to inform you that the sick female lion has died,” Salih further said in the post. “The other female is getting better and the male is OK.”

Salih has now decided to start an online campaign called #SudanAnimalRescue in order to raise awareness and to help save the remaining animals, which is slowly gaining momentum.

Many people expressed concern for the animals and demanded that be moved to a better location:

Park officials and vets, meanwhile, have blamed Sudan’s economic crisis for the situation, saying that the lions have gone weeks without the proper amount of food and medication. They also informed that some lions are believed to have lost more than two-thirds of their body weight.

“Food is not always available so often we buy it from our own money to feed them,” said Essamelddine Hajjar, a manager at the park.

African lions are classified as a “vulnerable” species by the International Union for Conservation of Nature. According to an AFP report, the species’ population dropped by 43 percent between 1993 and 2014, and only around 20,000 are still alive today.

Dealing with a shortage of foreign currency and soaring food prices, Sudan is currently in the middle of an economic crisis.
