The 20-second clip opens with the Smurfs happily dancing and singing their theme song accompanied by birds and butterflies.

But then planes appear which drop bombs on the idyllic scene, setting fire to the blue-skinned characters' houses.

One character, Smurfette, is killed and others run for cover while a baby is left crying in the middle.

The ad finishes with the message: "Don't let war affect the lives of children."
