Thousands of protesters from Australia to India rallied to voice their support for Palestinians on Sunday, as Israel mounted a ground assault in Gaza and the death toll from air strikes climbed.

In Sydney an estimated 3,000 people demonstrated outside the city's Town Hall to condemn the military offensive, shouting "Free, free Palestine; free, free Gaza" and holding signs declaring "Shame Israel Shame".

"Israel is targeting the civilians of Gaza with these bombings, and that is shameful and that is what we condemn," Greens party senator Lee Rhiannon told the crowd.

In Indonesia, the world's most populous Muslim nation, about 500 people marched in the capital Jakarta shouting "Allahu Akbar" (God is great) and carrying Palestinian flags and posters of children killed in the offensive.

"This is a show of solidarity for our Muslim brothers and sisters in Gaza who are being oppressed by Israeli occupiers. We Indonesian Muslims share their suffering and pain," activist Adityo Nugroho told AFP.

In Hong Kong organizers of a pro-Palestinian rally said about 300 people, mostly from the city's Muslim community took part.

"We came to support our sisters and brothers in Gaza and our request is that they stop the killing of innocent children women in men in Gaza," a protester said.

In the Indian capital New Delhi about 100 protesters, mainly students, gathered outside the Zionist embassy carrying placards stating "We are with you Gaza" and "Say no to Zionist genocide".

Protests were also held in Tokyo and Malaysia on Friday.
