The Pittsburgh Zoo & PPG Aquarium says its 10-year-old African lion has died.
Razi's death was announced Wednesday.
Officials say the lion had suffered for years from seizures. He had a grand mal seizure on Sunday and fell in his exhibit, breaking his jaw.
Veterinary and zoo staff determined that it wasn't in Razi's best interest to attempt the difficult surgery he would need.
Razi was first diagnosed with idiopathic epilepsy after experiencing a seizure in the spring of 2013, a year after he arrived at the zoo with his brother, Ajani, who is still at the facility.
