A major row broke out between leaders of the Taliban over the make-up of the group's new government in Afghanistan, senior Taliban officials told BBC. The argument between the group's co-founder Mullah Abdul Ghani Baradar and a cabinet member happened at the presidential palace, they said.

There have been unconfirmed reports of disagreements within the Taliban's leadership since Mr Baradar disappeared from public view in recent days. These have been officially denied.

The Taliban seized control of Afghanistan last month, and have since declared the country an "Islamic Emirate". Their new interim cabinet is entirely male and made up of senior Taliban figures, some of whom are notorious for attacks on US forces over the last two decades.

One Taliban source told BBC that Mr Baradar and Khalil-ur-Rahman Haqqani - the minister for refugees and a prominent figure within the Haqqani network - had exchanged strong words, as their followers brawled with each other nearby.

  A senior Taliban member based in Qatar and a person connected to those involved also confirmed that an argument had taken place late last week. The sources said the argument had broken out because Mr Baradar, the new deputy prime minister, was unhappy about the structure of their interim government.

It has been said that the row stemmed from divisions over who in the Taliban should take credit for their victory in Afghanistan.

Mr Baradar reportedly believes that the emphasis should be placed on diplomacy carried out by people like him, while members of the Haqqani group - which is run by one of the most senior Taliban figures - and their backers say it was achieved through fighting.

Mr Baradar was the first Taliban leader to communicate directly with a US president, having a telephone conversation with Donald Trump in 2020. Before that, he signed the Doha agreement on the withdrawal of US troops on behalf of the Taliban.

Meanwhile, the powerful Haqqani network is associated with some of the most violent attacks that have occurred in Afghanistan against Afghan forces and their Western allies in recent years. The group is designated by the US as a terrorist organisation.

Its leader, Sirajuddin Haqqani, is the interior minister in the new government.

Rumours about a fallout have been spreading since late last week, when Mr Baradar - one of the best-known faces of the Taliban - disappeared from public view. There was speculation on social media that he might have died.

The Taliban sources told BBC that Mr Baradar had left Kabul and travelled to the city of Kandahar following the row.

In an audio recording purportedly of Mr Baradar released on Monday, the Taliban co-founder said he had been "away on trips". "Wherever I am at the moment, we are all fine," he said.

The BBC was not able to verify the recording, which was posted on a number of official Taliban websites.

The Taliban have maintained that there was no argument and that Mr Baradar is safe but have released conflicting statements on what he is currently doing. A spokesman said Mr Baradar had gone to Kandahar to meet the Taliban's supreme leader, but later told BBC that he was "tired and wanted some rest".

Many Afghans will feel they have good reason to doubt the Taliban's word. In 2015, the group admitted covering up their founding leader Mullah Omar's death for more than two years, during which time they continued to issue statements in his name.

Sources told BBC that Mr Baradar was expected to return to Kabul and might appear on camera to deny that any argument had happened.

Speculation remains over the Taliban's supreme commander, Hibatullah Akhundzada, who has never been seen in public. He is in charge of the Taliban's political, military and religious affairs.

Meanwhile, Afghanistan's acting foreign minister on Tuesday called for international donors to restart aid, saying the international community should not politicise their assistance. More than $1 billion in aid was pledged for the country on Monday, following warnings from the United Nations of a "looming catastrophe".

500 Afghans evacuated from Uzbekistan

The United States said Tuesday it had evacuated nearly 500 "military and civilian" Afghans from Uzbekistan, while the ex-Soviet country declared there were now no Afghan refugees on its territory.

The days leading up to the Taliban's capture of Kabul caused scenes of chaos in Afghanistan's Central Asian neighbours Uzbekistan and Tajikistan, as soldiers loyal to the crumbling government fled over state borders in military aircraft. 

Uzbekistan had mostly withheld comment on the number and status of the refugees as it looked to cultivate ties with the Taliban next door.

But a US embassy spokesman told AFP Tuesday it had evacuated 494 "military and civilian" Afghans out of Uzbekistan's southern Termez airport with the Uzbek government's help.  

"The evacuation was completed September 12-13," the spokesman told AFP by telephone, making no comment on the final destination of the refugees.

Uzbek foreign ministry spokesman Yusup Kabulzhanov on Monday confirmed the evacuation in comments to the privately-owned Kun.uz outlet.

"All Afghan refugees have left the territory of Uzbekistan", he said, without giving figures. 

A staffer at Afghanistan's embassy told AFP last month that up to 1,500 Afghans might have crossed into Uzbekistan illegally after the Taliban secured control of the northern stronghold Mazar-i-Sharif in mid-August and began beating a path towards Kabul. 

In a rare statement on the refugees in August, Uzbekistan said it had returned 150 people to Afghanistan at their own request and following talks with the Taliban to guarantee their safety.

- Thousands of Afghans in Tajikistan: EU -

Tajikistan, which has eschewed official contacts with the Taliban, has been similarly secretive about the number of refugees it has taken in.

The European Union's delegation in the country said on Tuesday that it was providing 160,000 Euros in humanitarian aid funding "to benefit up to 5,000 displaced Afghans" in two Tajik provinces bordering Afghanistan.

The EU statement cited the UN Refugee Agency (UNHCR) as saying that "up to 50,000 refugees could be registered in Tajikistan after the total withdrawal of American and NATO troops by the end of 2021". 

The statement comes after Interior Minister Ramazon Hamro Rahimzoda earlier this month criticised international donors for failing to help Tajikistan house refugees.

Afghanistan is set to dominate discussions at the summit of the Shanghai Cooperation Organisation -- a bloc that includes four ex-Soviet Central Asian countries, China, India, Pakistan and Russia -- hosted by Tajikistan this week.
