Israel has tightened its siege of northern Gaza in the face of warnings from the UN and other aid agencies that hundreds of thousands of Palestinian lives at are risk, raising questions over whether the Netanyahu government’s ultimate war aims include territorial expansion.

The IDF says it is hunting Hamas militants but suspicions are growing that Israel is putting into practice a blueprint it had officially distanced itself from, known as the “generals’ plan”.

The plan, named after the retired senior officers promoting it, was intended to depopulate northern Gaza by giving the Palestinians trapped there an opportunity to evacuate and then treating those that stayed as combatants, laying total siege.
