Scientists have discovered a reservoir of liquid water on Mars - deep in the rocky outer crust of the planet.

The findings come from a new analysis of data from Nasa’s Mars Insight Lander, which touched down on the planet back in 2018.

The lander carried a seismometer, which recorded four years' of vibrations - Mars quakes - from deep inside the Red Planet.

Analysing those quakes - and exactly how the planet moves - revealed "seismic signals" of liquid water.

TUNIS, Aug 10 (Reuters) - Tunisia's electoral commission said on Saturday it had preliminarily accepted only three presidential candidates, including incumbent Kais Saied, amid widespread criticism of what the opposition says are moves to exclude serious contenders.

The commission said it had accepted the candidacies of Saied and Zouhair Magzhaoui, who is seen as close to Saied, and Ayachi Zammel for the Oct. 6 election, while rejecting 14 others.

Zammel is the head of the Azimoun party, and has not previously been regarded as a influential politician.

Prominent politicians, including Mondher Znaidi, Imed Daimi, Abdel Latif Mekki, Karim Gharbi, Safi Said, Kamel Akrout and Nizar Chaari, said the interior ministry refused to provide them with the criminal record details required by the commission as a new condition to run.

They accused the authorities of seeking to return Tunisia to the years of dictatorship and sham elections that were the norm before a revolution in 2011.

FREETOWN, Aug 10 (Reuters) - A military court in Sierra Leone has sentenced 24 soldiers to lengthy prison terms for their roles in a failed attempt to overthrow the government of President Julius Maada Bio last November.

KIGALI, Aug 11 (Reuters) - Rwanda's President Paul Kagame was sworn into office on Sunday for a five-year term, after a landslide win in last month's election extended his near quarter century in office.

The 66-year-old former rebel leader won the July poll with 99.18% of the vote, after eight other candidates including his most vocal critics were barred by the electoral commission.

KAMPALA, Aug 11 (Reuters) - The death toll from a landslide at a vast garbage dump in Uganda's capital Kampala has risen to 21, police said on Sunday, as rescue workers continued to dig for survivors.

After torrential rain in recent weeks, a huge mound of garbage at the city's only landfill site collapsed late on Friday, crushing and burying homes on the edge of the site as residents slept.

President Yoweri Museveni said in a statement he had directed the prime minister to coordinate the removal of all those living near the garbage dump.

It's the first standoff in summer games history and it took a nail-biting U.S. women's basketball win, in the final action of Paris 2024, to make happen.

PARIS — The United States and China each won 40 gold medals, in the first Summer Games draw in Olympics history, with America pulling into a tie Sunday with victory in the last event, women’s basketball.

Changes to the curriculum could mean schoolchildren analyse articles in English lessons to weed out fabricated stories, learn how to identify fake news in computer classes and analyse statistics in maths.

Bridget Phillipson said she is launching a review of the curriculum in both primary and secondary schools to embed critical thinking across multiple subjects and arm children against "putrid conspiracy theories".

It means schoolchildren may analyse articles in English lessons to help learn how to them weed out fabricated clickbait from accurate reporting.

Computer lessons could teach them how to spot fake news sites and maths lessons could include analysing statistics in context.

• Moscow forces fight Kyiv's troops in Kursk for sixth day
  • At least 13 injured in Kursk from downed missile
  • Russian authorities rush to evacuate residents

KYIV, Aug 11 (Reuters) - President Volodymyr Zelenskiy said Ukraine had launched an incursion into Russian territory to "restore justice" and pressure Moscow's forces, in his first acknowledgement of Kyiv's surprise offensive into the western Kursk region.

Moscow's forces on Sunday were in their sixth day of intense battle against Kyiv's largest incursion into Russian territory since the start of the war, which left southwestern parts of Russia vulnerable before reinforcement started arriving.

Russian authorities rushed to evacuate residents and imposed a sweeping security regime in three border regions on Saturday, while Belarus, a staunch ally of Moscow, sent more troops to its border with Ukraine, accusing Kyiv of violating its air space.

In his nightly video address, Zelenskiy said he had discussed the operation with top Ukrainian commander Oleksandr Syrskyi, vowing to respond in kind after Russia launched its full-scale invasion of its neighbour in February 2022.

Concrete structures, also known as "Lego blocks", will be placed along Latvia's border with Russia and Belarus.

Construction is underway on the first phase of the Baltic Defence Line in Latvia's easternmost region of Latgale.

Pyramidal obstacles made of reinforced concrete have been transported on trucks to the area, where they will be used to protect the external borders of Latvia and Europe.

For now, the army is placing the obstacles together in depots owned by municipalities or state institutions near the border with Russia and Belarus.

They will then be placed at intervals along the border in places the National Armed Forces considers necessary.
