Human rights activist Ni Yulan 'barred from leaving' China

Chinese rights lawyer Ni Yulan, who has spent years advising victims of forced evictions, has just been awarded the US State Department's International Women of Courage Awards.

But she was not allowed to go to the ceremony in Washington earlier this week to collect it in person.

She has told the BBC she was illegally prevented from travelling.

Our Beijing correspondent John Sudworth went to meet her.
