Seen from the air, Kabul is something of an anti-climax, coming as it does after the dramatic sharp-edged peaks of the Hindukush that seem to almost brush the wings of the aircraft as it passes. The city is a squat, brown huddle of buildings below us, a nondescript desert town that could be anywhere.

That, and the fact that the Afghans getting off the flights are heavily outnumbered by bulky soldiers and aid workers with well-thumbed passports. For once, our Indian credentials get a special welcome. The immigration official&rsquos eyes light up at my Mumbai address. But what really makes him happy is my name. &ldquoKhan What are you doing in India Don&rsquot you belong in Afghanistan&rdquo he chuckles, ignoring the growing line behind me. Finally, I am let through with a smile and a cheery &ldquowelcome home&rdquo.
