Jakarta – The Indonesian Islamic Propagation Institute (LDII) and the Indonesian Mosque Council (DMI) have called on Muslims in the country to launch a protest against an incident which marred the 9th anniversary of the Sept. 9 terror attack on the US over the weekend.

"The incident is intolerable as it violated the human rights. The US government should not stay silent in response to the harassment against a religion," LDII chairman Prasetyo Sunaryo said in a press statement.

He was commenting on six conservative Christians who tore some pages from a Koran in a protest outside the White House on Saturday. The incident came as a Christian hard-line group canceled its plan to burn a Koran to mark the anniversary of the Sept. 9 attacks.

Prasetyo said the LDII and DMI would file a protest with the US Embassy in Jakarta later this week as the incident departed from President Barack Obama's view concerning ties between the US and the Muslim world.

"We demand evidence of President Obama's words. The incident may spark anger among mujahids and Islamic fundamental groups," Prasetyo warned. He called on Indonesian Muslims to remain calm and take measures to maintain religious harmony in the country.
