Israel last week cut off all supplies of goods to the territory of over 2 million people, in an echo of the siege it imposed in the earliest days of its war with Hamas.

Israel cut off the electricity supply to Gaza, officials said Sunday, affecting a desalination plant producing drinking water for part of the arid territory. Hamas called it part of Israel’s “starvation policy.

The move, which will mainly affect a single wastewater treatment plant, appeared intended to put pressure on Hamas.
