Starving in rusted cages, their ribs like shadows and eyes fading, the lions waited—unseen cries lost in a world that reacted too late.

At an impoverished, forlorn zoo in Sudan’s capital, the park’s few remaining lions are starving in rusted cages — their ribs protruding, eyes glassy and skin flaccid, desperate for food and water. The unsettling images, shared on social media by a local animal rights advocate, drew impassioned responses from thousands around the world. But it wasn’t enough to save two lionesses at the Khartoum zoo, said local activist Zuhair al-Sarag.
