More than 400 people have been killed by Israeli air strikes on Gaza, according to the Hamas-run health ministry
The Israeli military says it's hitting "terror targets" across Gaza after talks to extend the ceasefire failed - it's the biggest wave of strikes since 19 January, when the ceasefire began
Prime Minister Benjamin Netanyahu's office says Israel will "act against Hamas with increasing military strength", accusing Hamas of "repeated refusal to release our hostages", and of rejecting proposals to extend the ceasefire
Hamas accuses Israel of attacking "defenceless civilians", and says mediators should hold Israel "fully responsible" for "violating and overturning" the ceasefire
Israel says 59 hostages are still being held in Gaza, with up to 24 believed to be alive - a group representing hostage families accuses the Israeli government of choosing "to give up the hostages" by launching new strikes
Donald Trump is yet to comment on Israel's strikes - National Security Council spokesman Brian Hughes says Hamas "chose war" by not releasing hostages
Jon Donnison: Is this the war resuming?
We're expecting Israeli Prime Minister Benjamin Netanyahu to deliver a statement in the next hour.
When that happens, we'll bring you his key points right here - plus you'll be able to watch along live at the top of this page.
Stay with us until then as we continue to bring you the latest.
Image source, United NationsFollowing on from our last post, Palestinian ambassador to the UN Riyad Mansour has also been speaking at the Security Council meeting - saying last night's strikes on Gaza mean "the same images are back to haunt us".
"Small children on gurneys, little siblings injured and disoriented trying to comfort and reassure each other, entire families killed, children, mothers, fathers, searching for their loved ones under the rubble, not knowing if they are dead or alive," he says.
He tells the UN that there must be no reduction in Gaza's territory or forced displacement, accusing Israeli Prime Minister Benjamin Netanyahu of being "self-serving" and caring more about his political survival than the return of hostages.
Mansour also says US President Donald Trump has prioritised the release of hostages in the region - something the US's interim ambassador to the UN also said (you can read that in our last post).

At a UN Security Council meeting, acting US Ambassador to the UN Dorothy Shea says Hamas has rejected every proposal and deadline in recent weeks. That includes a plan to extend the ceasefire beyond Ramadan and Passover to allow time to negotiate a permanent truce.
Responding to claims of indiscriminate attacks by Israel’s military, Shea says the Israel Defense Forces (IDF) are targeting Hamas positions and that "it is well known that Hamas continues to use civilian infrastructure as launching pads."
"President Trump has made clear that Hamas must release the hostages immediately or pay a high price, and we support Israel in its next steps," she tells delegates.
Earlier, Israel's government spokesman David Mencer said the country's return to fighting Hamas was "fully coordinated with Washington". Trump is yet to comment on the strikes.

We've reported some of these names already, but the key Hamas figures now confirmed killed in the overnight Israeli airstrikes are as follows:
Meanwhile, Palestinian Islamic Jihad (PIJ) - an allied armed group of Hamas - also confirmed the death of its spokesman Naji Abu Seif, otherwise known as Abu Hamza.

Image source, InstagramA video verified by our team shows graphic images of first aid workers digging through rubble to find what appear to be dead bodies at the site of a school in northern Gaza.
The Al-Tabaeen school in Gaza City has been used to house displaced people during the conflict between Hamas and the Israeli military.
We know the video was taken at the site as you can see a distinctive courtyard in the footage, which matches previous images of the school.
Although the exact timing of the footage is unclear, it appears to have been taken at night and the first version of it we can find was from early on Tuesday.
The site has been hit previously - in August last year 80 people were reportedly killed in a strike there, according to the Hamas-run health ministry.
At the time, the Israel Defense Forces (IDF) said, without providing evidence, it had struck a "Hamas control centre" there. The IDF is yet to comment on the latest incident at the site.
We heard earlier that the Israeli government had given the White House notice before launching overnight strikes on Gaza, after an Israeli official told the BBC’s US partner CBS News as much.
Israel has since doubled down on that claim, with government spokesman David Mencer saying the return to fighting was "fully coordinated with Washington" - and thanking the Trump administration "for their unyielding support for Israel" and for the "fortification of Israel's security".
The alliance is "stronger than ever", he told reporters. Trump is yet to comment on the strikes.
BBC World Service's Emir Nader, who was at the news conference, asked Mencer for his response to the families of hostages who say the government has given up on those still being held by Gaza and is pulling out of a deal that would have brought everyone home.
"It is Hamas that took these hostages," Mencer responded to the question, arguing that Hamas "could set them free" if it wanted to. "Hamas cannot be trusted," he added.
Image source, EPA-EFE/REX/ShutterstockIsrael's President Isaac Herzog has taken to social media, saying the Israeli military's "renewal of fighting" in Gaza has two main goals: "The critical moral goal of returning the kidnapped, and of course restoring full security to all residents of the State of Israel."
In the post, he acknowledges that the overnight strikes on Gaza are "a cause for concern for many", and that's why it's important for him "to emphasise that fighting is not an end in itself" - but a tool to achieve the goals Herzog outlines above.
He also urges the government to listen to the families of the hostages and calls on all Israelis to show sensitivity towards them in "this difficult time".
We can now bring you some images from outside the Knesset (Israel's parliament), where members of the Hostages and Missing Families Forum have gathered to protest.
They're holding up signs, some with images of those still being held by Hamas, calling on the Israeli government to "bring them home".
In an earlier statement, some of the families said officials had chosen to "give up" on hostages by launching the overnight strikes on Gaza.
Here's what we're seeing:

With families of the hostages still in Gaza protesting against Israel's decision to resume fighting (see our last post), here's a reminder of how many people were freed as part of the first phase of the ceasefire - and how many remain.
Some 25 Israeli hostages were released, alive, between 19 January 2025 - when the long-awaited Israel-Hamas ceasefire began - and the end of February.
Among them were Eli Sharabi (shown above)and Emily Damari, a British-Israeli dual citizen who was one of the first people to be released under the deal.
Hamas also handed over the bodies of another eight hostages. Five living Thai nationals were released too - but this was part of a separate deal.
In exchange, around 1,900 Palestinian prisoners were freed from Israeli jails - images showed emotional family reunions in the occupied West Bank.
Who remains? Israel says Hamas is still holding 59 hostages - all but one who were taken during the 7 October 2023 attacks - with 24 believed to still be alive.

Samuel outside the protest - 529 is a reference to the number of days since the 7 October attacks and the kidnapping of hostages by Hamas
Families of hostages have been meeting Israeli politicians in the parliament in Jerusalem, while a large crowd protests outside.
Lishi Lavie-Miran - wife of Omri Miran who was taken captive from Kibbutz Nahal Oz on 7 October - angrily told members of the Knesset that if her husband is killed "she would not be responsible for her actions" if one of them "dared to approach her".
Outside, Samuel, an army reservist and history teacher, is among those shouting for the hostages to be brought back immediately.
He says he wants to be an example for his students. "They are 18 years old, they’re going to be serving in the army in the coming months and I believe they shouldn’t be serving in this kind of war," he says.
He adds that he sees this war as political: "It’s not about Israel’s security - Benjamin Netanyahu has his own reasons for this war, and he is corrupt. We need to stop the war and bring back the hostages."
Noga Kaplan, a 22 year-old student at Hebrew University, holds a sign saying "Bibi must go".
She says that re-starting the war is "the worst thing that can happen for the hostages" and calls on the government, Hamas, and the US to continue the ceasefire agreement and the hostages exchange.

Reporting from the White House
Image source, Bernd Debusmann Jr/BBC NewsGood morning from the White House, where a small trickle of reporters is starting to stream in on a day in which the world's headlines are being dominated by news from Ukraine, and Gaza.
So far, reaction from the US to the resumption of hostilities in Gaza has been relatively muted.
In a brief statement to US media outlets, National Security Council spokesman Brian Hughes said that "Hamas could have released hostages to extend the ceasefire but instead chose refusal and war".
In a Fox News interview, Press Secretary Karoline Leavitt also confirmed that Israeli officials notified their US counterparts about the operation.
"As President Trump has made it clear - Hamas, the Houthis, Iran and all those who seek to terrorise not just Israel, but also the United States of America, will see a price to pay. All hell will break loose," she added.
We've not, however, heard directly from President Donald Trump. There is very little on his public schedule today - although he is due to be speaking to Vladimir Putin this afternoon - but at 15:30 EDT (19:30 GMT), he's scheduled to sign executive orders.
While for now the event is closed to the press, we've often seen these events turn into extended question-and-answer sessions in the last few weeks.
We can bring you some more reactions from around the world to Israel's strikes on Gaza.
Iran's Foreign Ministry Spokesperson Esmaeil Baghaei says the US has "direct responsibility" for the "continuation of genocide in the occupied Palestinian territories".
Egypt's Ministry of Foreign Affairs Spokesperson Tamim Khallaf says Israeli air attacks constitute "a blatant violation" of the ceasefire agreement and represent "a dangerous escalation".
Jordan has been following "Israel's aggressive and barbaric bombing of the Gaza Strip" since last night, the AFP news agency reports, citing government spokesman, Mohammed Momani, who underlines "the need to stop this aggression".
Saudi Arabia condemned Israel's bombing "areas populated by defenceless civilians", without "the slightest regard for international humanitarian law".
The EU's aid commissioner, Hadja Lahbib, calls for an end to renewed violence and a return to a ceasefire, saying civilians in Gaza have "endured unimaginable suffering".

Image source, ReutersThe Otzma Yehudit (Jewish Power) party, led by former national security minister, Itamar Ben-Gvir, will return to Netanyahu’s coalition government, it announced in a joint statement with Prime Minister Benjamin Netanyahu's Likud party.
The far-right party announced it would leave Netanyahu's coalition in January in protest at the Gaza ceasefire.
Ben-Gvir wanted a complete military victory over Hamas, and called for a cut-off of humanitarian aid to Gaza until the hostages were released.
Ben-Gvir welcomed Israel's return to "intense fighting", following its strikes on Gaza last night.
"As we said in recent months, when we withdrew: Israel must return to fighting in Gaza: this is the right, moral, ethical and most justified step," he said in a post on X.

It's approaching 12:30 in London and 14:30 in Gaza. If you're just joining us, here's a recap of what has happened:
Israel issued new evacuation orders, shown in red, earlier on Tuesday
We're now seeing a joint statement from the Israel Defense Forces (IDF) and the Israel Security Agency (Shin Bet).
They say they are continuing to strike "terror targets" across the Gaza Strip.
The statement adds that in the past few hours, they have hit "terrorist cells, launch posts, weapons stockpiles, and additional military infrastructure" used to "plan and execute attacks against Israeli civilians and IDF soldiers".
"At this time, the IDF and ISA are striking terror targets throughout the Gaza Strip," the statement concludes.

BBC Arabic's Gaza Lifeline programme has been hearing from Gazans about the fresh wave of Israeli air strikes.
"Everyone was filled with fear, unsure of where to go," a man tells the programme, saying the attack happened as he woke for the pre-dawn Ramadan meal.
Another man, Essam Abu Odeh, says he was suddenly woken by the attack at 02:00 local time.
"My daughter woke me up, warning me about the bombardment. We quickly took shelter against the walls, fearing rubble might fall on us," he recalls.
Mohammed Zaquot, director general of the Gaza Strip's hospitals, says the injured include people with burns and fractures, with many still waiting for surgery.
"The attacks were so sudden that the number of medical staff available was inadequate for the scale of these large strikes, and additional teams were called in immediately to assist," he says.

BBC Verify has been authenticating video and images being shared on social media after Israeli airstrikes.
We have geolocated material in three locations, although the attacks are reported to have happened across the entire Gaza Strip.
In one clip, which is filmed near Nasser Hospital in Khan Younis in the south, we hear several blasts in the distance.
In another video, a dead or unconscious girl is carried in the arms of a man towards the Indonesian Hospital in northern Gaza.
A third video shows a building in southern Gaza, in the outskirts of Rafah, with smoke coming from part of its upper floor.
A key part of our process is checking the material surfacing on social media is new. Each of the videos we have verified have had multiple keyframes reverse searched to ensure it is not old footage resurfacing.

The Hamas-run health ministry has given an update on the number killed.
In a post on Telegram, it says 404 people have been killed by the Israeli air strikes.
On its Whatsapp channel, it gives a slightly higher figure of 413.
The ministry adds that some victims are still trapped under the rubble.

In a newly released statement, Hamas says the United States "bears full responsibility for the massacres" in Gaza, after it emerged Israel briefed the US on the strikes prior to launching them.
The statement says this "exposes the falsity of its claims about caring for de-escalation".
"The international community is urged to take immediate action to hold the occupation and its supporters accountable for these crimes against humanity," it adds.
