The United Nations says it will resume aid deliveries to rebel-held areas of northern Syria via Turkey after reaching agreement with Damascus -- a deal that raises concerns among relief groups who want Syrian authorities kept out of the process.

Under a 2014 agreement, most international aid had passed through the Bab al-Hawa crossing from Turkey without the authorization of Damascus.

A spate of high-profile visits by US officials to Saudi Arabia underscores how ties have warmed amid talks over a potential deal that would see the Gulf kingdom recognise Israel, analysts say.

Less than a year after US President Joe Biden warned of unspecified "consequences" for Riyadh during a dispute over oil supply, he is dispatching top aides to meet Saudi royals at a rapid clip.

Over the weekend, his national security adviser, Jake Sullivan, landed in Jeddah for a summit on Ukraine –- his third visit to Saudi Arabia in just a few months.

Thousands of people displaced by 12 years of war are stuck in squalid, unofficial camps in Syria's Kurdish-held northeast, languishing in extreme poverty and largely cut off from international assistance.

"We've been completely forgotten," said Rahma al-Hammud, 33, standing at her tent -- a shoddy patchwork of worn-out fabric, tarp and old fertiliser bags crudely sewn together.

"Our children get sick over and over again. They get fever, diarrhoea and vomiting," said the widowed mother of four.

Israel's army said Tuesday it demolished the home of a Palestinian accused of killing a soldier and his brother in the occupied West Bank, which has seen months of violence.

Clashes occurred during the overnight incursion to destroy the residence of Abdel Fatah Khroushah in the Askar camp for Palestinian refugees, in the northern city of Nablus, the military said.

The army said "explosive devices were hurled, and live fire was shot at the forces, who responded with riot dispersal means."

Russia claimed Tuesday it had struck a command post in the eastern Ukraine town of Pokrovsk, as Kyiv said the missile attack had hit civilian targets and killed at least seven people.

Pokrovsk, which had a pre-war population of around 60,000, sits just 40 kilometres (25 miles) from the eastern front line, where Moscow says it is gaining ground and repelling Ukrainian attacks.

Around 200 Tunisian bakers staged a sit-in Monday after a government decision to stop selling them subsidised flour, a move threatening the closure of hundreds of bakeries.

"We are being forbidden from producing baguettes," Mohamed Jamali, president of the Association of Modern Bakeries, told AFP in Tunis where the protest took place.

Last week the ministry of commerce banned some 1,500 privately-owned bakeries that produced European-style breads and pastries from purchasing subsidised flour, ending a practice that had lasted for more than a decade.

More than 3,000 United States military personnel have arrived in the Red Sea aboard two warships, part of a beefed up response from Washington after tanker seizures by Iran, the US Navy said Monday.

The deployment adds to a growing US military buildup in tense Gulf waterways vital to the global oil trade and led Tehran on Monday to accuse the US of inflaming regional instability.

The US military says Iran has either seized or attempted to take control of nearly 20 internationally flagged ships in the region over the past two years.

Torrential rains have destroyed more than 450 homes in Sudan's north, state media reported Monday, validating concerns voiced by aid groups that the wet season would compound the war-torn country's woes.

Changing weather patterns saw Sudan's Northern State buffeted with heavy rain, causing damage to at least 464 houses, state-run SUNA news agency said.

It described the vast region bordering Egypt and Libya as "a desert area that rarely received rain in the past, but has been witnessing devastating rains for the past five years".

Five people including two policemen were killed and at least 11 others injured during the collapse of several buildings in Iran's capital, local media reported on Monday.

The policemen were securing the planned demolition on Sunday of "unauthorised buildings" in Tehran's southwest, ISNA news agency said. Another news agency, Tasnim, said two of the officers were killed.

The overall "toll from the collapse" has reached five, spokesman for Tehran's fire department, Jalal Maleki, told Fars news agency.

Oil firm Saudi Aramco on Monday announced profits of $30.08 billion for the second quarter, a sharp fall from the same period last year when prices surged after Russia invaded Ukraine.

The 38-percent year-on-year decline "mainly reflected the impact of lower crude oil prices and weakening refining and chemicals margins", the largely state-owned company said in a statement published on the Saudi stock exchange.

The decline followed a drop of 19.25 percent in first-quarter net profit.
