Rally in protest at disappearance of Hong Kong booksellers

Thousands of people in Hong Kong have attended a protest rally following the disappearance of five booksellers from a shop known for selling works critical of China.

Chanting "say no to political kidnapping", the protesters marched to the offices of Beijing's representative in Hong Kong.

Under the "one country, two systems" principle Hong Kong is supposed to enjoy high degrees of autonomy from China since it took over from Britain.
