A pair of 400-pound gorillas escaped their habitat at a Kansas City zoo on Sunday.

They escaped from their habitat after a doorway separating their holding area from the keepers' area was left unlatched.

The zoo keepers climbed a retaining wall to get to safety.

Meanwhile, zoo visitors were hustled into a safe area.

In the end, no one was hurt and the gorillas were herded back into their enclosure after about four hours.
