DHAKA: A student leader vowed Wednesday to step up Hong Kong’s huge pro-democracy protests, including a possible occupation of government offices, unless the city’s leader steps down within a day, as support for the movement grew around the world.

The announcement came as tens of thousands of defiant demonstrators poured onto the streets on China’s National Day.

‘If our Chief Executive and the central government (China) do not respect and listen to our people's opinion, we will consider having different operating actions in future days, including occupying other places like important government offices,’ said Agnes Chow of the Scholarism student movement, reports The Straits Times.

Chow said the deadline for Chief Executive Leung Chun-ying was ‘today or tomorrow’.

Chan Kin-man, co-founder of the pro-democracy Occupy Central movement which co-organised the demonstrations, said any escalation would be ‘an action initiative by the students’ and called for it to be peaceful. But he ruled out any dialogue with Leung.

‘We can talk to anyone in the government except him... resign for the sake of Hong Kong.’

Leung has faced mounting calls to step down and has been criticised for failing to engage with protesters, after their ‘Umbrella Revolution’ campaign for unfettered universal suffrage sparked the biggest civil unrest in the semi-autonomous Chinese city for decades.

Wednesday was a holiday marking the 65th anniversary of the founding of Communist China, and Thursday is also a holiday in Hong Kong.
