Israel is threatening to cut off water and electricity to Gaza and tighten its siege of the enclave to pressure Hamas into releasing the remaining hostages on more favourable terms.
The Israeli military had on Sunday shut all routes for food and other aid, including fuel, to enter Gaza after Prime Minister Benjamin Netanyahu decided not to continue negotiating the second phase of a ceasefire with Hamas within a framework agreed in January.
Israel is now considering cutting off a critical water line and power line, two people familiar with the deliberations within the Israeli government said. This would leave 2.2mn Palestinians dependent on dwindling supplies of fuel to pump water from the small number of tube wells that survived the war.
