Israel said Wednesday it would call up 60,000 reservists and extend the service of others for a planned offensive in Gaza City and other heavily populated areas, ratcheting up pressure on Hamas as ceasefire talks show signs of progress .
The expansion of Israeli operations is likely to bring even more death and destruction to Gaza, around 75% of which is already largely destroyed and controlled by Israel. A wider offensive would also force more people to flee and further disrupt the delivery of humanitarian aid as experts say the territory is at imminent risk of famine .
