Dramatic footage has emerged of Chinese activists breaking into a house where the wife of a jailed Nobel peace laureate is being held against her will.

Liu Xia has been under house arrest in her Beijing apartment since her husband Liu Xiaobo was awarded the Nobel Peace Prize in 2010.

It's the first time in more than two years that friends have been able to see Liu Xia.

It's believed her husband irritated the Chinese government as a writer and human rights activist, openly calling for an end to Communist party rule.
