Jakarta, Indonesia - About 100 Indonesian Islamists demonstrated outside the US embassy in Jakarta on Friday and threatened "jihad" or holy war if a US Christian group goes through with threats to publicly burn the Koran.
The Dove World Outreach Center's planned Koran burning on the ninth anniversary of the September 11 terror attacks would unleash uncontrollable rage from Muslims around the world, a spokesman for the protesters warned.
"No one will be able to control this reaction," said Roni Ruslan of the Hizbut Tahrir, an international radical organisation that advocates the introduction of sharia or Islamic law.
"We urge the US government and Christian leaders to stop the crazy plan from this small sect. It's an insult to Islam and to 1.5 billion Muslims around the world," he added.
Protesters shouted "God is greater" while holding banners that read "Destroy burners of the Koran" and "Answer the Koran burning with Jihad".
The Florida-based church group's Facebook page bears the motto "Islam Is Of The Devil" and has more than 6,000 fans.
Indonesia is the world's largest Muslim-majority country.
