There's no point in me trying to paraphrase this. Here's the lede from this article…
The people of Belgium have been left reeling by a public service commercial featuring the Smurfs, in which the blue-skinned cartoon characters' village is annihilated by warplanes. The 25-second commercial is the work of UNICEF, and is to be broadcast on TV across Belgium next week as a public fundraiser. It is intended as the keystone of a drive, by UNICEF's Belgian arm, to raise about $145,000 for the rehabilitation of former child soldiers in Burundi. The animation was approved by the family of the Smurfs' late creator, "Peyo."
Here's a link to a version of the commercial that runs a little over a minute and a half but contains the Smurfs sequence in the middle. The whole video is in still pictures like a filmstrip and I'm not sure if this is a special "no movement" edition for the Internet or if this is the way it's going to air wherever it airs.
Not being able to understand the language or the context, I don't have an opinion about it other than that it's really weird. If you didn't know it was authorized by Peyo's heirs, you'd figure it was one of those Robert Smigel cartoons on Saturday Night Live. I will note though that back when a 90-minute bloc of Smurfs programming anchored the NBC Saturday morning schedule and trounced the competition, executives at CBS and ABC used to fantasize about something very similar.
