Anxious families of hostages have called for a “nationwide day of stoppage” in Israel on Sunday to express growing frustration over 22 months of war.

The plan would envisage people moving from an enclave shattered by almost two years of war with Israel to a nation in the heart of Africa riven by political and ethnically-driven violence.

Israel is intensifying its strikes on Gaza City, the territory’s largest urban centre, as it plans to seize it.
