DUBAI (Reuters) -UN Security Council permanent members China and Russia backed Iran on Monday in rejecting a move by European countries to reimpose UN sanctions on Tehran loosened a decade ago under a nuclear agreement.

A letter signed by the Chinese, Russian and Iranian foreign ministers said a move by Britain, France and Germany to automatically restore the sanctions under a so-called "snapback mechanism" was "legally and procedurally flawed".

ANKARA (Reuters) -Turkish President Tayyip Erdogan told Iranian counterpart Masoud Pezeshkian on Monday that he believes it was useful for Tehran to continue nuclear negotiations and that Ankara would maintain its support for Iran on the matter, Turkey's presidency said.

In a meeting on the sidelines of a summit of the Shanghai Cooperation Organisation (SCO) in China, Erdogan also said that cooperation between the neighbours, namely in energy, was to the benefit of both sides, the presidency said in a statement.

ISTANBUL (Reuters) -In a brightly lit treatment room at a private hospital in Istanbul, doctor Erdal Dilekci makes dozens of small, quick incisions on a patient's back as part of a centuries-old therapy known as wet cupping.

The patient, 26-year-old nurse Furkan Ali Sayan, lies quietly as the doctor then places eight suction cups designed to draw out toxins and ease his neck and back pain.

Over the next 15 minutes, the cups slowly fill with blood.

KFAR MALIK, West Bank/JERUSALEM (Reuters) -Palestinians in the Israeli-occupied West Bank are facing severe water shortages that they say are being driven by increasing attacks on scarce water sources by extremist Jewish settlers.

Across the West Bank in Palestinian communities, residents are reporting shortages that have left taps in homes dry and farms without irrigation.

Tunisia's brutalist landmark the Hotel du Lac -- a 1970s postcard icon said to have inspired a desert-roving vehicle in "Star Wars" -- is being demolished, sparking calls from architects, historians and activists to save it.

Built by Italian architect Raffaele Contigiani in central Tunis, the concrete-and-steel inverted pyramid opened in 1973 during a push to boost post-independence Tunisia's tourism industry.

Its daring silhouette has since enraptured brutalism and modernist architecture admirers from across the globe.

Fierce Mediterranean winds forced a Gaza-bound flotilla carrying humanitarian aid and hundreds of pro-Palestinian activists, including environmental campaigner Greta Thunberg, to return to Barcelona, organisers said on Monday.

Around 20 vessels left the Spanish city on Sunday aiming to "open a humanitarian corridor and end the ongoing genocide of the Palestinian people" amid the Israel-Hamas war, said the Global Sumud Flotilla -- sumud being the Arabic term for "resilience".

(Reuters) -More than 800 people were killed and thousands more injured as a major earthquake struck southeastern Afghanistan late on Sunday, one of the worst such disasters in the country in recent years.

As authorities scramble to rescue survivors, here is a look at what happened, and the devastation the tremors caused.

WHERE DID THE QUAKE STRIKE?

MADRID (Reuters) -An aid flotilla of dozens of boats that had set sail for Gaza on Sunday carrying aid and pro-Palestinian activists, including climate campaigner Greta Thunberg, has returned to port in Barcelona due to stormy weather, organisers said on Monday.

"We conducted a sea trial and then returned to port to allow the storm to pass. This meant delaying our departure to avoid risking complications with the smaller boats," the Global Sumud Flotilla Mission said in a statement, adding winds had been up to around 35 mph (56 kph).

Yemen's Huthi rebels held a funeral on Monday for their prime minister and 11 other senior officials killed in an Israeli air strike that decimated its political cabinet.

Twelve coffins draped in flags were displayed at Sanaa's Al-Shaab mosque, as masked gunmen patrolled the area and thousands of mourners flooded in.

Huthi prime minister Ahmed Ghaleb Nasser al-Rahawi, nine ministers and two cabinet officials were killed as they attended a government meeting in the Sanaa area on Thursday.
