At least 28 people, including children, have died in a wave of Israeli military strikes throughout the Gaza Strip, according to Gaza's civil defence agency.

A school sheltering displaced families was among the facilities struck, killing eight people including four children over the weekend, the agency said.

It comes as the UN issues a plea for Israel to cease its attacks in the vicinity of a hospital in Gaza's north.

The Israeli military claimed a Hamas command centre was inside the compound of the Musa bin Nusair school in Gaza City, and has not commented on reports of attacks by the hospital.

"Hamas systematically violates international law," the Israel Defense Forces (IDF) said on social media, adding that Israel's response would be to "act with force and determination against the terrorist organizations".

Gaza's civil defence agency spokesperson Mahmoud Bassal told the AFP news agency that the school had been repurposed as a shelter for Palestinians displaced by the war.

One displaced man who had been staying at the school, Abu, told BBC Arabic that the attack came while he was asleep.

"We were sleeping peacefully, then suddenly we woke up to the sound of a very powerful explosion," he said.

Another man Mahmoud said he was asleep in a tent in the schoolyard when the attack took place.

"Stones and shrapnel were flying, the school's walls fell on our heads," he told BBC Arabic.

On Sunday, Pope Francis condemned the Israeli attacks on Gaza for a second day in a row.

He expressed pain thinking "of such cruelty, to the machine-gunning of children, to the bombing of schools and hospitals".

The director of the Kamal Adwan hospital, Dr Hussam Abu Safiya, said its generators had been hit and claimed the Israeli army was targeting the fuel tank.

The head of the World Health Organization (WHO), Dr Tedros Adhanom Ghebreyesus, issued a plea to the IDF to cease attacks in the vicinity of the hospital.

Saturday night's reports of "bombardment near Kamal Adwan Hospital and order to evacuate the hospital are deeply worrisome," he said in a statement on social media.

"We call for an immediate ceasefire in the vicinity of the hospital and to protect the patients and health workers."

The hospital's director also released a statement that said Israeli forces were treating the hospital "as if we were a military installation".

"Anyone who steps outside the hospital is at risk of being targeted," Dr Hussam Abu Safiya said.

He added that relocating the operations of the hospital would jeopardise the patients, and called for health staff "be allowed to operate without the threat of evacuation".

Israel has not commented on the reports of an evacuation order.

The BBC has approached the IDF for comment.

Palestinian groups involved in the fighting have told the BBC that a ceasefire deal is "closer than ever".

More than 45,000 Palestinians have been killed during the 14-month war between Israel and Hamas, according to figures from Gaza's Hamas-run health ministry.

The war began when Hamas-led gunmen carried out an unprecedented attack on southern Israel on 7 October 2023, during which about 1,200 people were killed and 251 others were taken hostage.

The rhetoric on social media following the murder of healthcare CEO Brian Thompson in New York earlier this month has been "extraordinarily alarming", US Homeland Security Secretary Alejandro Mayorkas says.

"It speaks of what is really bubbling here in this country, and unfortunately we see that manifested in violence, the domestic violent extremism that exists," he told CBS's Face the Nation on Sunday.

Some on social media have celebrated Luigi Mangione, the man accused of shooting dead Mr Thompson, and shared anger at America's private health insurers.

Mayorkas said he was "alarmed by the heroism that is being attributed to an alleged murderer of a father of two children on the streets in New York".

Mr Thompson, the 50-year-old CEO of the largest US health insurer UnitedHealthcare, was gunned down outside a Manhattan hotel early on 4 December triggering a massive manhunt for the killer.

Mr Mangione, 26, was arrested days later in Pennsylvania and flown to New York where he is facing both federal and state charges, including first-degree murder in furtherance of terrorism.

Investigators accuse him of carrying out a targeted killing, pointing to evidence that suggests a long-held animosity towards the US healthcare industry. On social media, support for Mr Mangione has often been accompanied by grievances and complaints with the health insurance sector.

• The dark fandom behind CEO murder suspect

"We have been concerned about the rhetoric on social media for some time," Mayorkas said on Sunday. "We've seen narratives of hate. We've seen narratives of anti-government sentiment. We've seen personal grievances in the language of violence."

Mayorkas, whose homeland security department is in part responsible for protecting Americans from domestic terrorism, said his department sees a "wide range of narratives" that "drive some individuals to violence."

"It's something that we're very concerned about," he said. "That is a heightened threat environment."

But the 65-year-old, whose time at the helm of the department will end next month, stressed that Mr Thompson's killing was "the actions of an individual [and] not reflective of the American public".

Mr Mangione will remain behind bars in New York as his lawyers said last week that they would not present an application for bail. He is in federal custody at the Metropolitan Detention Center Brooklyn, the same facility where Sean 'Diddy' Combs is being held.

He will likely be assigned a roommate and have daily visits from medical and psychological services, law enforcement sources told the BBC's US partner CBS.

While New York does not have the death penalty, he faces four federal charges, including murder and stalking, which could make him eligible for the punishment. He also faces multiple state charges.

He is expected to be arraigned on those state charges in New York on Monday. Mr Mangione faces 11 counts, including murder in the first degree and murder as a crime of terrorism.

Whether it's opening presents or the long-awaited Christmas dinner, the festive season involves plenty of things that could go wrong.

It's the little things that count at this time of year - and your etiquette is no exception.

The BBC has chatted with experts about potentially awkward moments you might face over the next few days, so you can try to avoid them.

A common festive issue is getting a present you do not like. Is it best to tell the person who gave it to you, or lie that you love it?

It depends on how well you know the person who gave you the gift, according to Rupert Wesson from professional coaching company Debrett's.

To lie - or not to lie

"There are some people [to whom] you can say the gift isn't for you, and for some you have to smile and tell them a little white lie that you like it," he tells the BBC.

But whatever you do, "don't make a funny face" at the gift when you open it, warns etiquette coach Laura Windsor.

"Just pretend you do [like it], and make a little comment on how useful the gift will be," she says. "The etiquette is always to be kind."

Both etiquette coaches say it's fine to give an unwanted present to charity or re-gift it for someone else in the future.

Mr Wesson suggests you should "always" keep a gift receipt when buying a present just in case - and he has these words of reassurance: "We can't all be perfect at buying exactly the right thing."

Open up about the cost

While the cost of turkey and Brussels sprouts have gone down this year, the price of root vegetables have gone up and some families are feeling the pinch this winter.

Ms Windsor advises that you can make a "Christmas pot" that everyone contributes to ahead of the big day.

Alternatively, she says you could ask each guest - or family member - to buy an item of food or drink each.

"There's no shame in this day and age in saying: 'I'm getting people together for Christmas, would you be able to provide this?'," Mr Wesson adds.

Stay upbeat - and avoid certain subjects

Sometimes petty arguments can flare up when the whole family is together - perhaps having eaten or drank too much.

Ms Windsor says "don't take it personally, just try to smooth it over," adding that you should not give people the "power to keep them complaining".

She advises to try and change the topic of conversation, but to avoid difficult subjects.

"You've got to keep the conversation upbeat."

If there are any existing tensions among the guests ahead of 25 December, Mr Wesson suggests attempting to address them upfront when you're putting together your plans before Christmas Day.

"Almost make the invitation [to guests or extended family] conditional that someone isn't going to kick off," he says.

Is it possible to say 'thank you' too much?

Ms Windsor advises against saying "thank you" to the host too much as it "loses its value".

She suggests showing your appreciation to the host in other ways, including offering to help them with anything, bringing a gift for them - such as a bottle of wine or a plant - and mingling with other guests.

"Mix it up a bit by complimenting them on the quality of the food," Mr Wesson says.

"Appreciation of how good the food is goes a long way."

Both etiquette experts advise sending a thank you note to the host after Christmas Day which is something that Mr Wesson calls "the gold standard of thank yous".

Be upfront about dietary requirements

If you have dietary requirements, such as being vegetarian or vegan, let whoever is hosting your Christmas dinner know ahead of time and not on 25 December, Ms Windsor stresses.

"It's about prevention, preventing discord - everything has to be organised beforehand," she says.

Mr Wesson adds: "It does fall to the host to really identify what the requirements are and then the host can plan."

Ms Windsor says that if there is any tension between people about the dietary requirements, "be empathetic" but stop the conversation.

"If they make a non-cordial remark, don't take it to heart."

The Christmas dinner rules

If your stomach is growling for Christmas dinner and you're growing impatient at how long it's taking to cook, Mr Wesson suggests you could offer to help.

"Then you're going to find the lay of the land and maybe suggest we can share something [to eat ahead of Christmas dinner]," he says.

But when you're finally tucking into the dinner, what do you do if you don't like it?

Say "yes" when asked if you're enjoying the food, Ms Windsor says.

"If you don't want to eat it, leave it," she adds - and you could always just say you've "had enough" to eat.

Mr Wesson advises to "try and draw as little attention" as possible to the fact you are not eating the meal.

To prevent this situation happening, try to see if the host will let everyone plate up their own food and then "don't pile too much on" in case you dislike it.

What to do if cards and gifts arrive after Christmas

Work, childcare, school - lots of things in life can get in the way and cause you to miss the cut-off date for sending Christmas cards and presents in time for 25 December.

Ms Windsor says organisation is "very, very important" because it shows that "you've put a lot of thought and put in the time and effort to make sure they get it in time for Christmas".

However, she says that you have to "take into account people's daily situation".

Mr Wesson says that "better late than never is the way ahead" but advises people to send a message to whoever the card or present is addressed to, letting them know it is on the way and apologise for the lateness.

'The golden rule'

Christmas Day all comes down to preparation - both organising the day and planning around family relationships, Mr Wesson says.

"It's trying to expect the best but also accept the possibility things might go a little awry," he says.

"Often these things aren't really that serious and often doesn't ruin the whole day."

"The golden rule: treat others as you'd like to be treated," Ms Windsor adds. "You won't go wrong with that."
