Middle East crisis live: Israeli attacks kill at least 31 people in Gaza, medics say

Nearly half of those killed were reported to be in northern Gaza, where the IDF has been conducting an intense assault

There are mounting concerns over whether the Israeli government's ultimate war aims in Gaza include territorial expansion, as the IDF's siege on the northern part of the territory - under sweeping evacuation orders - intensifies.

Here is an extract from a report by my colleagues Malak A Tantesh and Julian Borger, who explore these concerns further:

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.
