An investigation by CNN has revealed Hamas trained for the October 7th attacks at six Gaza military sites.
Israel faces growing criticism for an apparent 'intelligence failure' before the attack.
The investigation adds to it, as some sites were close to the most heavily patrolled section of the Israel-Gaza border.
One of the training sites was just 720 meters from the most fortified and patrolled section of the Gaza-Israel border.
The Hamas attack on Israel last weekend killed over 1,300 people in Israel.
