One of the German aid workers, Georg Taubmann, said the airlift followed a dramatic rescue by Northern Alliance forces.

He said the Taleban had moved them from Kabul on Monday, just before it fell to Northern Alliance troops.

The plan had apparently been to take them to the Taleban stronghold of Kandahar, but they only got as far as Ghazni, about 80 kilometres (50 miles) from the capital.

They were locked up, first in a steel container in freezing conditions, and then in the local jail.

The aid workers were greeted by their families

But on Wednesday, Mr Taubmann said, there was an anti-Taleban uprising in Ghazni, and the eight workers were released by opposition fighters.

The opposition leader in the town informed the International Red Cross, who arranged for their evacuation by US special forces.

They were airlifted to Pakistan and arrived at Chaklala military air base near Islamabad early on Thursday morning.

They were driven to their embassies in a motorcade to meet relatives and officials.

The Taleban seized material from the aid workers' office

They had been the only foreign aid workers left inside Taleban-controlled Afghanistan.

Their position had become considerably more perilous following the start of US-led military action against the Taleban in the wake of the 11 September attacks.

On hearing the news, Nancy Cassell, mother of aid worker Dayna Curry, said she was relieved to hear of her daughter's safety.

"They're on their way here. I'm happy and I want to get ready to go where they come in," she said.

Washington had demanded that the Taleban release the eight unconditionally.

Taleban officials had said they would protect the Westerners in the event of any American attack.
