Afghanistan is marking the 10th anniversary of the start of the US-led invasion of the country amid growing security concerns and questions over what the next decade will hold. For some Afghans, the Friday anniversary of the offensive against the Taliban and al-Qaeda marks a time of reflection on what the war has meant for their country.

A British government review of the Afghan conflict is to warn that there are "significant risks" of civil war or a Taliban takeover of the south and east of the country after Nato withdraws its combat troops at the end of the 2014.

After the initial US invasion Taliban recognising defeat wanted to talk peace: a formal surrender, the transfer of vehicles and weapons, an end to fighting in Kandahar, all in return for assurances their leaders could be able to return to their villages. That night Obaidullah sent bread for Karzai, in a gesture of conciliation. In retrospect, it was a tantalising opportunity for a smooth post-Taliban transition and, perhaps, a novel political dispensation. But it wasn't to be. Furious after the 9/11 attacks, the US war machine pursued the Taliban hard. Karzai, the new leader, acquiesced. And the Taliban leadership slunk across the border into Pakistan to lick their wounds and plan the resurgence that is racking the country today.
