Although this isn't the most likely spot to make a kill, it's worth knowing about if ever the opportunity presents itself.

This is the spot and your attention is on the regeneration location that is found in the boiler room which is just behind this wall.

Throw up some mines to near the left corner. Make sure to use a few mines so that the explosion will engulf an opponent on the other side.

I would strongly suggest that nobody would survive this explosion. Wouldn't you agree?

If you ever pass through this area with an explosive when a player is about to regenerate, don't pass up the opportunity. Try out this kill through a wall. I've never done it, but maybe you can. If you can get me the video!
