Israel’s energy minister said Sunday that he would immediately cut off electricity to the Gaza Strip, in an apparent effort to pressure Hamas on negotiations after the first phase of a ceasefire deal expired on March 1.

Israel says it has cut the flow of electricity to the last facility in Gaza that was still receiving power from the Israel Electric Corporation.

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.
