Israel continued to prepare for a ground assault on the Hamas-controlled Gaza Strip a week after an attack by Hamas militants.
The UN, aid emergencies and human rights organisations have urged world leaders to intervene as Palestinians struggle to flee ahead of an attack that Prime Minister Benjamin Netanyahu said would "demolish Hamas".
It comes after Hamas fighters killed 1,300 men, women and children and seized hostages in Israeli towns in the worst attack on civilians in the country's history.
Israel has said more than 1,300 of its citizens have been killed since Saturday 7 October, including children, with more than 3,400 wounded, while National Security Council head Tzachi Hanegbi said around 150 to 200 hostages are being held in Gaza after being kidnapped.
As of Sunday morning, 2,329 Palestinians have been killed according to the Palestinian health ministry, including children, with 9,042 wounded, in Israeli air strikes on the blockaded enclave since 7 October.
More than one million people have been displaced in the Gaza Strip in the last week, the UN said.
Here are the main stories from today:
1. Israel 'restores water supply' in southern Gaza
On Sunday it was reported that Israel had restored the supply of water to southern Gaza. US national security adviser Jake Sullivan told CNN that his Israeli counterparts had informed him of the decision, and Israel’s energy minister Israel Katz said the move was agreed between prime minister Benjamin Netanyahu and US president Joe Biden.
Prime Minister Benjamin Netanyahu convened Israel's expanded emergency cabinet for the first time on Sunday, saying the national unity on display sent a message at home and abroad as the country geared up to "demolish Hamas" in Gaza.

2. Up to 10 British nationals feared to be among Hamas hostages
The Israeli Defence Forces confirmed that 126 people were taken hostage when Hamas militants crossed the border last weekend.
Reports have suggested that up to 10 British nationals are among the hostages, but on Sunday Foreign Secretary James Cleverly declined to give an exact number and said the situation remained uncertain, telling Sky News: "That is not an unreasonable estimate of the kind of number of people that we’re talking about."

3. Hamas accused of halting evacuees
The Israeli Defence Forces (IDF) shared a recording of a Gaza resident claiming Hamas fighters were stopping people from leaving the northern part of the territory. In the recording, the man can be heard telling an IDF officer that militants were taking people's ID cards and car keys away after holding them up.
Similar claims of Hamas preventing evacuations were also made by US national security adviser Jake Sullivan in an interview with CNN.
4. Foreign secretary warns against glorifying terrorism
The Foreign Secretary repeated warnings against glorifying terrorism. James Cleverly told Sky News' Trevor Phillips On Sunday Morning programme that he and the government shared a passion 'about a better life for the Palestinian people', but added: "However, glorifying murder and terrorism is no benefit to the Palestinian people, just as Hamas are no friend to the Palestinian people."
His warning comes after Home Secretary Suella Braverman told police chiefs that waving a Palestinian flag on the street in the UK "may not be legitimate" if it is deemed to be in support of Hamas or acts of terrorism.

5. Hundreds gather in Parliament Square in support of kidnapped hostages
Hundreds of people gathered in Parliament Square on Sunday to express their solidarity with Israel and those taken hostage by Hamas.
It comes a day after thousands of people marched through London in support of Palestine. Police had warned that anyone showing support for Hamas or deviating from the route could face arrest.
Where is Gaza?
Gaza, also known as the Gaza Strip, is a densely-populated Palestinian enclave on the eastern coast of the Mediterranean, north-east of the Sinai Peninsula.
Bound by the Mediterranean Sea to the west, Israel to the north and east and Egypt to the south, it is just 25 miles long and six miles wide.
Gaza is one of two Palestinian territories. The other is the Israeli-occupied West Bank.
