As we reported earlier, the Hamas-run Health Ministry in Gaza says 1,055 people have been killed, external in the Gaza Strip and 5,184 injured since Israel began its air strikes.

Image source, ReutersNadiya is the mother of a five-year-old boy and three-month old baby in Gaza.
She says the only way to calm the older boy, as Israeli air strikes land, is to tell him "the sound of an explosion comes a few moments after it actually happens".
It is the kind of knowledge no five-year-old should be expected to understand, but for Nadiya, it is the best way to cope.
On Monday night, Nadiya says she heard her neighbours running down the stairs shouting: "Evacuate! Evacuate!"
The young mother hesitated for a couple of seconds. Then she burst into tears.
Eventually, she left the building with her two children, but said she couldn't recognise the neighbourhood as buildings around her block had been levelled.
She's now trying to make her way to her parents' house. But, she says: "Where can you hide when death is coming from the sky?"
In Israel, Menashe and Merav Ram held a funeral yesterday for their 28-year-old son Omri, who was killed by Hamas militants at the Supernova music festival on Saturday.
Early on Saturday, when Hamas began firing rockets into Israel, Omri called his parents, telling them of the attack.
In a second phone call he said: "Dad, it's more serious. People are injured."
Menashe said Omri was going to jump in the car and drive to safety. But then the connection became weak and they lost contact.
"I felt like something was happening," Merav told the Today programme earlier. "I told Menashe something was wrong."
Of the attackers, Menashe said: "I don't know if we can call these kinds of people humans. Humans do not do these kind of things to boys and girls that only wanted to celebrate.
"They will not be forgiven for what they've done."

British-Palestinian surgeon, Ghasan Abu Sitta, says the hospital where he's working in Gaza has turned into a refugee camp.
"People are afraid and so they're bringing their families to stay in the compound of the hospital as a safe space," he told the Today programme earlier.
The surgeon said there was a "continuous stream of wounded people", but that his Shifa hospital was already at capacity - like most other hospitals in Gaza.
"Gaza has around 2200, 2500 beds and we've already had 4500 wounded," Abu Sitta said.
More now on what's been happening at Israel's border with Lebanon.
Israel's military says, external its aircraft attacked an observation post inside Lebanon belonging to Hezbollah. The IDF also fired at the area.
Israel says it's in response to a fresh rocket attack by Hezbollah - which Hezbollah says was done in retaliation for Israeli killing three of its fighters in skirmishes with Israel this week.
This is the fourth day of violence at the border.
We've just had an update from the Palestinian health ministry - it says 1,055 people have been killed and more than 5,100 others injured since Israel's retaliatory air strikes began on Saturday.
The Ministry of Health said earlier nearly 60% of the injured people in Gaza were women and children.

These images were taken near a destroyed police station where a gun battle took place.
The death toll in Israel has reached 1,200, with more than 2,700 people injured.
Image source, ReutersAs we reported earlier, there's been more violence at Israel's border with Lebanon this morning.
The Lebanese militia Hezbollah says it fired two missiles on an Israeli army post in response to losing three of its fighters in skirmishes with Israel this week.
Israel is now shelling an area in southern Lebanon in response.

We reported yesterday evening that part of the Islamic University in Gaza City had been destroyed by Israeli air strikes.
The Israeli Air Force has now confirmed the strike in a post on X, external, formerly known as Twitter.
The IAF says they attacked the university because it "serves as a major training centre for Hamas engineers," and is "an important centre of political and military power" .
It also says Hamas used the site to produce weapons.

As Israel responds to the missile fired by Hezbollah from Lebanon, sirens are now sounding in northern Israel - to warn Israelis of incoming attacks.
Half an hour ago, we reported that a missile had been fired from Lebanon into Israel, which Hezbollah has since said it was behind.
Israel's military now says it is attacking Lebanese territory in response - and Lebanon's state media says two areas are being shelled.
"The area around Dhayra is being bombarded by enemy artillery, while the area around Yarin is being hit with phosphorus shells," Lebanon's National News Agency reported. The BBC has not confirmed those details.

As we've just reported, we know there are 17 British nationals dead or missing after the Hamas attack on Israel.
So far we've only had a few names confirmed. One of those who died was 20-year-old Nathanel Young, who attended school in north London before moving to Israel to serve in the military.
Another was Bernard Cowan, a Scottish grandfather who grew up in Glasgow before settling in Israel with his family.
Among those reported missing are Jake Marlowe, who was working as a security guard at a music festival, and Daniel Darlington, whose family believe he was killed.
The BBC has learned from an official UK source that after the weekend's attack by Hamas there are 17 dead or missing UK nationals, with children among them.
The previous estimate was "more than 10" British nationals dead or missing.
Away from Gaza, Israel's military says a missile has been fired from Lebanon towards an Israeli military post at the border.
The anti-tank missile struck near the village of Arab Al-Aramshe, the IDF said, external - at the other end of the country from where Hamas has launched its attacks.
It's not the first time violence has erupted at the Lebanon border in recent days.
Hezbollah - which is backed by Iran, but proscribed by Israel and much of the West as a terrorist group - has fired rockets into Israel since Hamas began its assault.

There was a very dangerous escalation last night in the northern part of Gaza City.
Hundreds of air strikes destroyed a neighbourhood, according to a local authority here. More than 50 people were killed overnight, most of them civilians.
We are still unable to reach that area, but we have been watching from the rooftop, where overnight air strikes were non-stop.
We saw hundreds of people walking to the south of city, which they believe is much safer, going to hospitals and schools.
The UN is trying to accommodate 200,000 displaced people - that's about 10% of the population in the Gaza Strip.
People are without electricity, water supplies and food. They are queuing at bakeries where they get small amounts of food. Banks are giving small amounts of money, and petrol stations small amounts of fuel.
The minister of health said all of the medical centres and hospitals will be run out of medicine in 24 hours.
