Israel's military said Wednesday that it will call up tens of thousands of reservists and extend the service of others ahead of an expanded military operation it will carry out in Gaza City. Defense Minister Israel Katz approved plans to begin a new phase of operations in some of Gaza’s most densely populated areas,

This move comes amid international concerns about the humanitarian crisis in Gaza, where many residents are displaced and facing famine.

Israel will call up around 50,000 reservists for its new Gaza City offensive, and call-up letters will be sent out as soon as the coming days, an Israeli military official said on Wednesday, adding that the reservists' draft will begin in September.
