Noor Jehan, one of the last four African elephants in captivity left in Pakistan, died on Saturday. The 17-year-old elephant fell ill four months ago and "should have been under treatment for a long time," a zoo official says.

"He was unable to get up on his own. Despite our efforts and the endless work of the team in the area, we could not help her recover," the zoo says of Noor Jehan's partner, Mabhubala.
