More than a fifth of the global ocean has become darker over the past two decades, according to University of Plymouth research.The process, known as "ocean darkening", occurs when changes to the ocean's upper most level reduce the depth at which sunlight can travel.

The study, published in Global Change Biology, found 21% of the global ocean had become darker between 2003 and 2022.Reasons for ocean darkening were believed to be down to factors such as changes in algal bloom dynamics, shifts in sea surface temperatures and artificial light, researchers said.The study found more than 9% of the ocean - an area similar in size of Africa - had seen a reduction in light by more than 164ft (50m).

A further 2.6% of the ocean saw a reduction of more than 328ft (100m), it said.While the precise implications of the changes were not wholly clear, researchers said large numbers of the planet's marine species and ecosystem services could be affected.

Dr Thomas Davies, associate professor of Marine Conservation at the university, said: "There has been research showing how the surface of the ocean has changed colour over the last 20 years, potentially as a result of changes in plankton communities.

"But our results provide evidence that such changes cause widespread darkening that reduces the amount of ocean available for animals that rely on the sun and the moon for their survival and reproduction."US President Donald Trump said on Friday that "a lot of people were starving" in Gaza. The Israeli government has repeatedly rejected claims there is a food shortage in Gaza.

Victoria Rose, a British reconstructive surgeon working at Nasser hospital in Khan Younis, told BBC Radio 4's Today programme that her team were "exhausted" and staff had lost a "considerable amount of weight"."The children are really thin," she said. "We've got a lot of youngsters whose teeth have fallen out.

"A lot of them have quite significant burn injuries and with this level of malnutrition they're so much more prone to infection and they've got so much less capacity to heal."Israel's Prime Minister Benjamin Netanyahu had said on 5 May that Israel was preparing an "
