Oh and before this "Hamas said they planned and killed these kids" lie goes any further, try and actually READ the articles you post to refute it.
1 - the story originates from Times of Israel, reporting on the "confession" under torture of Hussam Kawasme, the supposed ring leader.
2 - The story was then that Hamas had given money for the operation, but the operation required no money. Pick up three lads and kill them. Not expensive.
3 - Then there is a statement from some knob in Turkey Saleh Al-Arouri an exiled hamas "leader"
This is the confession you are alluding to, but it is not. It's a daft pratt in Turkey doing israels work for them.

The two men were affiliated with the Hamas militant group which runs Gaza. A group leader praised the kidnappings in August, though other top officials denied any advance knowledge.
