Citizens in the Gaza Strip are bracing for more electricity blackouts after Israel cut off fuel shipments to the territory's only power plant.
Israel has closed crossings into Gaza, making it likely that electricity would be completely cut off in the territory from about 1600 GMT, Palestinian officials said.
Israel's defence ministry closed the crossings on Sunday after Palestinian fighters fired rockets into southern Israel. No one was hurt in the attack.
"More than 30 per cent of the electricity supply in the Gaza Strip could not be guaranteed this evening," Jamal al-Kudari, head of a committee campaigning to end Israeli sanctions, said on Sunday.
