As thousands of citizens and foreign nationals attempt to flee Afghanistan, scenes outside Kabul airport have become increasingly desperate.

Since the Taliban took control of the country at the weekend and closed land border crossings, the capital's airport has become the only way out of the country for many.

But the militants have said they don't want Afghans to leave.

They have set up checkpoints on Airport Road - the main route to Hamid Karzai International Airport - and have attacked people.

The violence has left 12 people in the area dead - killed by gunshots or in stampedes - since Sunday, an anonymous Taliban official told Reuters news agency, meaning the journey to the airport is increasingly treacherous.
