Thousands of residents have fled Gaza City's southern Zeitoun neighbourhood, where days of continuous Israeli bombardment have created a "catastrophic" situation, the city's Hamas-run municipality has told the BBC.

At least 40 people were killed by Israeli attacks across the territory on Saturday, Gaza's civil defence agency said.

The Israeli military said it would begin allowing tents to be brought into Gaza by aid agencies again. Israel plans to forcibly displace a million people from Gaza City to camps in the south, according to BBC.

In Israel, a one-day general strike is due to be held in Sunday in protest of the government's plan to seize Gaza City.
