First Thing: Appeals for body bags amid fears of epidemic after Libya floods

Up to 20,000 people feared dead after devastating floods. Plus, Mitt Romney attacks Trump in resignation announcement

Good morning.

Rescue workers in the devastated Libyan city of Derna have appealed for more body bags after a catastrophic flood killed thousands of people and swept many out to sea.

International aid is slowly starting to reach the port city after Storm Daniel hit the northern coast of Libya on Saturday night.

“We actually need teams specialised in recovering bodies,” said Derna’s mayor, Abdulmenam al-Ghaithi. “I fear that the city will be infected with an epidemic due to the large number of bodies under the rubble and in the water.”

The city of about 100,000 has been devastated. Hichem Abu Chkiouat, the minister of civil aviation in the area, said the “sea is constantly dumping dozens of bodies”. An aid worker from Benghazi told the Associated Press: “Bodies are everywhere, inside houses, in the streets, at sea. Wherever you go, you find dead men, women and children.”

The disaster in Libya is the result of the “climate crisis meeting a failed state”, writes the Guardian’s diplomatic editor, Patrick Wintour.

• What are the current death toll estimates? The number of dead was feared to be between 18,000 and 20,000, Ghaithi said.

• Who is helping with aid efforts? Rescue teams had arrived from Egypt, Tunisia, the United Arab Emirates, Turkey and Qatar, the mayor said. The UK announced an initial $1.25m aid package.

• What is happening to injured people? Derna residents have been pleading for a new field hospital as the two existing hospitals have become makeshift morgues.

Mitt Romney condemns ‘demagogue’ Trump as he announces retirement

Senator Mitt Romney of Utah, a former presidential nominee and a rare relative moderate in the Republican party of Donald Trump, has said he will not run for a second term next year, depriving the party of one of its fiercest critics in Congress of the former US president and his political movement.

Amid increased scrutiny of the advanced age of many US politicians, Romney said it was time for a new generation to “step up [and] shape the world they’re going to live in”. He said he did not think a second term that would end when he was in his 80s could be as effective as his first.

“It’s pretty clear that the party is inclined to a populist demagogue message,” he told the Washington Post.

• How old is Romney? He is 76. That’s one year younger than Trump (77), four years younger than President Joe Biden (80) and five years younger than the Kentucky senator Mitch McConnell (81).

US federal judge rules revised Daca policy is illegal and halts new applications

A federal judge has declared illegal a revised version of a federal policy that prevents the deportation of hundreds of thousands of immigrants brought to the US as children.

The US district judge Andrew Hanen agreed with Texas and eight other states suing to stop the Deferred Action for Childhood Arrivals (Daca) program. An appeal against the ruling was expected to go to the supreme court, sending the program’s fate before the high court for a third time.

It follows the Biden administration’s efforts to change the program after Hanen ruled in 2021 that Daca was illegal – saying it had not been subject to required public notice and comment periods – but Hanen was not satisfied with the changes.

• How many people are enrolled in Daca currently? There were 578,680 people enrolled at the end of March, according to US Citizenship and Immigration Services.

• Which states are trying to ban Daca? Texas, Alabama, Arkansas, Louisiana, Nebraska, South Carolina, West Virginia, Kansas and Mississippi.

• What does the ruling mean? The judge barred the government from approving any new Daca applications, but left the program intact for existing recipients during the expected appeals process.

Don’t miss this: Tech entrepreneur Bryan Johnson on his controversial plan to live for ever

Bryan Johnson knows that you think he is weird. He rises at 4.30am, eats all his meals before 11am, and goes to bed – alone – at 8.30pm, without exception. In the intervening hours, he ingests more than 100 pills, bathes his body in LED light, and sits on a high-intensity electromagnetic device that he believes will strengthen his pelvic floor. This is all done in the service of slowing his rate of ageing until, he hopes, one year of chronological time can pass while his biological age stays the same. His ultimate goal? “Don’t die,” he tells Joel Snape.

Climate check: Earth ‘well outside safe operating space for humanity’, scientists find

An assessment of Earth’s life support systems – such as climate, water and wildlife diversity – found that six out of nine “planetary boundaries” had been broken because of human-caused pollution and destruction of the natural world. The assessment is based on 2,000 studies and was published in the journal Science Advances. The broken boundaries mean Earth’s systems have been driven far from the safe and stable state that existed from the end of the last ice age, 10,000 years ago, to the start of the Industrial Revolution.
