France is to hold a day of national mourning after Cyclone Chido devastated its Indian Ocean territory of Mayotte earlier this month.

French President Emmanuel Macron called for the nationwide remembrance during his visit to the island last week - where he was jeered by some islanders who criticised the slow delivery of aid.

It is feared hundreds, possibly thousands, of people died when Chido made landfall off Africa's south-east coast on 14 December bringing winds of up to 260 km/h (160mph) and 250mm of rainfall in the first 24 hours.

People across France will pay tribute and flags will be flown at half-mast in a show of solidarity at cities including Paris, Marseille and Lyon.

More than a week on from the storm survivors are struggling without water, communication and electricity while rescuers try to provide urgently needed assistance.

Mayotte, which lies between the African mainland and Madagascar, was already France's most impoverished territory before the cyclone struck.

Chido - the worst storm to hit the archipelago in 90 years - flattened areas where people live in shacks with sheet metal roofs and left fields of dirt and debris.

At least 31 people are reported by French officials to have died, but the death toll is expected to be much higher with thousands still missing.

After Mayotte the storm hit the African mainland, killing at least 94 people in Mozambique and 13 in Malawi.

Macron pledged to rebuild the island's devastated infrastructure and homes following his visit.

After touring the region in a helicopter to see the devastation, he said that Thursday was a day he would never forget.

During the visit he was heckled and faced calls to resign from locals who demanded more aid in devastated areas.

Macron responded by telling locals: "I had nothing to do with the cyclone. You can blame me, but it wasn't me."

Prime Minister François Bayrou said the tragedy of Mayotte is probably the worst natural disaster in the past centuries in French history.

More than 100,000 people remain in Red Cross shelters after their homes were destroyed.

New Zealand has rejected a proposal by the Cook Islands to introduce a seperate passport for its citizens while allowing them to retain New Zealand citizenship.

Cook Islands, a self-governing island Pacific nation, is in "free association" with New Zealand, which is responsible for the former's foreign affairs and defence.

Cook Islanders can also live, work and access healthcare in New Zealand.

Prime Minister Mark Brown had asked for Cook Islanders to have their own passports "to recognise our own people" - but New Zealand has said that is not possible unless the Cook Islands becomes fully independent.

Documents first released to local broadcaster 1News and seen by Reuters reportedly showed that Brown has for months been pushing for a seperate passport and citizenship for those in the Cook Islands, while hoping to maintain its relationship as a realm country of New Zealand.

Reports say tensions between both countries have been escalating over the issue, with leaders of both places holding a series of talks over the past few months.

"New Zealanders are free to carry dual passports, there are a number of New Zealanders who have their passports of other countries," Radio New Zealand reported Brown saying.

"It is precisely the same thing that we'll be doing," he had said.

However some Cook Islanders had criticised their government for a lack of consultation over the proposal.

Thomas Wynne, a Cook Island national who works in Wellington, told local news outlet Cook Islands News: "The real question is what do the people of the Cook Islands want and have they been consulted on this critical decision? Or will it be a decision made by the few on behalf of the many?"

Other Cook Island residents told 1News that they were worried that such a move would also affect access to services like their right to healthcare in New Zealand.

But on Sunday, New Zealand's Foreign Minister Winston Peters effectively brought the conversation to an end, announcing that a separate passport and citizenship is only available to fully independent and sovereign countries.

Any move to change the current relationship between the two countries would have to be put through a referendum, he added.

"Such a referendum would allow the Cook Islands people to carefully weigh up whether they prefer the status quo, with their access to New Zealand citizenship and passports, or full independence," he said in a statement to media outlets.

"If the goal of the government of the Cook Islands is independence from New Zealand, then of course that's a conversation we are ready for them to initiate."

According to 1News, Brown later responded to Peters' statement by saying the Cook Islands would "not be implementing anything that affects our important status [with New Zealand]".

Nearly 100,000 Cook Islands nationals live in New Zealand, while only about 15,000 live in Cook Islands themselves.

Another small Pacific island, Niue, also shares a similar relationship with New Zealand - it is internally self-governing but relies on Wellington for defence and most foreign affairs.

Self-governing territories elsewhere in the world, including Greenland and the Faroe Islands, which are part of the Kingdom of Denmark, and Puerto Rico, which is subordinated to the US in defence and foreign affairs.

Emergency doctors in the UK have issued a safety warning over water beads, which could be given to children as gifts over Christmas.

The beads, also known as jelly balls, sensory beads, or water crystals are marketed as crafting tools and homeware items - but also toys.

They are typically only a few millimetres but some can expand up to 400 times their original size in about 36 hours when exposed to liquid, creating a hidden danger. If a child swallows one, they can cause bowel obstruction and the consequences can be fatal.

The Royal College of Emergency Medicine (RCEM) advises that the beads should be kept well away from children aged under five.

The "safety flash" is for doctors to make sure they know what to look out for while on duty, but the college also wants parents and carers of be aware of the dangers.

The beads are not visible on X-rays.

They can also cause choking and have harmed children in the UK, with reports linking them to deaths overseas, the government's Office for Product Safety and Standards said in September.

Its safety alert added the beads should only used with older children or vulnerable adults under close supervision.

The RCEM advises parents and carers to seek medical attention immediately if there is any suspicion a child may have swallowed a water bead.

"Having seen the effects first hand, which can be devastating and detrimental, we are asking people to please think twice about the dangers these pose while selecting and gifting presents this season," Dr Salwa Malik, vice president of the RCEM, told PA Media.

The RCEM alert also highlights the potential danger to children and vulnerable adults of button or coin batteries and magnets, if swallowed.
