DUBAI (Reuters) -Iran's economy risks staggering into simultaneous hyperinflation and deep recession, officials and analysts say, as clerical rulers scramble to preserve stability with limited room to manoeuvre after a snapback of U.N. sanctions.

They followed a breakdown in talks to curb Iran's disputed nuclear activity and its ballistic missile programme. Diplomacy to resolve the deadlock remains possible, both sides say, though Iranian Supreme Leader Ayatollah Ali Khamenei has rebuffed U.S. President Donald Trump's offer to forge a new deal.

DUBAI (Reuters) -An Iranian student detained in France has been readied for a prisoner swap, an Iranian diplomat told semi-official Tasnim news agency on Tuesday, a day after Iran said there was necessary will to exchange prisoners with France.

LONDON (Reuters) -The British government on Tuesday removed Hay'at Tahrir al-Sham (HTS), the group which spearheaded the Syrian rebel alliance that helped oust President Bashar al-Assad, from its list of banned terrorist organisations.

LONDON (Reuters) -Eradicating polio is still possible despite significant funding cuts to the effort, global health officials said on Tuesday as they outlined how they will cope with the shortfall.

The budget of the Global Polio Eradication Initiative, a partnership including the World Health Organization and the Gates Foundation, will take a 30% cut in 2026 and has a $1.7 billion funding gap up to 2029, the organisation says.

The shortfall is largely driven by a pullback from foreign aid led by the United States and other wealthy donor governments.

(Reuters) -The Sudanese pound has shed nearly two-fifths of its value after a de facto embargo on flights from the army's wartime capital Port Sudan into the United Arab Emirates disrupted the vital gold trade, traders and Sudanese officials said.

The army relies on the UAE for hard currency from gold exports but also accuses it of backing the rival Rapid Support Forces paramilitary in a two-and-a-half-year civil war that has killed tens of thousands and displaced millions.

Turkey's President Recep Tayyip Erdogan was due in Doha late Tuesday as Ankara sought to acquire some of Qatar's used Eurofighter Typhoon jets, a Turkish security source told AFP.

Erdogan flew in from Kuwait and was expected to meet Qatar's Emir Sheikh Tamim bin Hamad Al Thani on Wednesday, according to the Turkish leader's office.

"Turkey has been trying to negotiate to acquire some of Qatar's used Eurofighters," the source told AFP, speaking on condition of anonymity because they were not authorised to talk to journalists.
