Israel says it is cutting off its electricity supply to Gaza. The full effects of that are not immediately clear, but the territory’s desalination plants receive power for producing drinking water.

Sunday’s announcement comes a week after Israel cut off all supplies of goods to the territory to over 2 million people. It has sought to press Hamas to accept an extension of the first phase of their ceasefire. That phase ended last weekend. Israel wants Hamas to release half of the remaining hostages in return for a promise to negotiate a lasting truce.

Hamas has pressed to start negotiations on the ceasefire’s more difficult second phase instead, which would see the release of remaining hostages from Gaza, the withdrawal of Israeli forces and a lasting peace. Hamas is believed to have 24 living hostages and the bodies of 35 others.
