Hong Kong protests in 60 seconds
Pro-democracy demonstrations have paralysed parts of Hong Kong since the end of September, amid a row about how the city's leader should be elected.
Elections are due in 2017 - but the Chinese government has issued a ruling limiting who can stand as a candidate, which has angered activists who want full democracy.
China has warned other countries not to support what it calls "illegal rallies".
BBC News explains the row - in 60 seconds.
