I doubt it is possible to truck a A320 on third world roads. Roads are very narrow with tight turns and electric, telecom and cable TV wires criss crossing everywhere. You can see some of the wires in the video.
There are news suggesting this happened at a turn, so most likely the wobble force snapped cable/buckled crane. I don't see any guide wires to control wobble.
In hindsight they should have removed as much weight as possible and use Mi-26 chopper to move it.
