In pictures: Hong Kong stand-off

Tens of thousands of protesters in Hong Kong continue their demonstrations over Monday night, angry at China for limiting their choice in 2017 elections.

There is a tense stand-off with police, as the pro-democracy protesters defied calls from the authorities to dismantle their camps and return home.

The demonstrators want China to abandon its plans to vet candidates for the post of chief executive in the 2017 polls.

The crowds on the streets of the Asian financial hub are a mix of students and members of the Occupy Central civil disobedience movement.

Early on Monday, Hong Kong police fired tear gas to disperse demonstrators.

Protests have sprung up in other parts of the city too. On Monday people continued to gather at Mongkok in Kowloon.

Some banks in the protest areas did not open for business.

Knock-on protests have taken place in Taiwan, where Taiwanese and Hong Kong students rallied in front of Hong Kong trade offices.

Protesters continued to use social media, despite attempts by the Chinese authorities to block popular websites, like photo-sharing service Instagram.
