Israel has cut off the electricity supply to Gaza. The move has affected a desalination plant producing drinking water for part of the arid territory. Hamas calls it part of Israel’s “starvation policy.” Sunday’s announcement came a week after Israel suspended supplies of goods to the territory of more than 2 million people. It's pressing Hamas to accept an extension of the first phase of their ceasefire. That phase ended last weekend. Hamas instead wants to start negotiations on the ceasefire’s more difficult second phase. Gaza has been largely devastated, and Israel has faced sharp criticism over cutting off supplies.
