An Israeli military official says the country’s top generals have approved plans to call up tens of thousands of reservists in order to begin a new phase of operations in some of Gaza’s most densely populated areas.

Israel has been in talks with African countries — many of which are themselves wracked by war and at risk of famine — about taking Palestinians in.
