“A thorn in his side.” Al-Duwairi: For these reasons, the periphery areas of Gaza disturb the occupation army. These areas are mostly agricultural, open, or contain buildings far apart, and therefore have a lower population density.
They contain a more effective and complex combat tunnel network, as they have multiple tunnel openings - which are not visible - and are used effectively to cause harm. There is no point in military pressure to release the prisoners detained in Gaza, and the only way to do that is an exchange deal.
