Chaos and confusion: The frenzied final hours of the Afghan government

The Taliban have announced a new government from Kabul, 20 years after they were driven from power.

For a generation that grew up with education, international investment and hope in a democratic future, reading that line must feel scarcely believable.

So how did the previous administration fall so quickly? The Taliban went from taking control of their first major city to arriving at the gates of Kabul in just 10 days.

But the capital, it was assumed, would be different. Most observers believed that Kabul would hold until a negotiated agreement could take place. On Sunday 15 August, that all changed. Within hours, the president and his top officials had fled. What was left of the Afghan army and police forces changed out of their uniforms, and went into hiding.

The Western-backed Afghan government, backed by trillions of dollars in military support and training over two decades, had simply melted away.

Through interviews with insiders who were there, BBC News has pieced together an account of how Afghanistan's government unravelled during those chaotic and frantic last few hours.
