Michael Bachelard – The spiritual leader of radical Islam in Indonesia has urged his supporters to greater acts of violence in retribution against the producers of the film Innocence of Muslims.

Speaking from his prison cell, firebrand cleric Abu Bakar Bashir called for the closure of the US embassy in Jakarta, which was briefly besieged by petrol-bomb-throwing protesters on Monday night.

While other Muslim clerics are calling for calm, Bashir, who is serving a 15-year jail term for establishing a terrorist training camp, told radical website aslami.org supporters should admire the action in Libya, which resulted in the death of the US ambassador.

"We have to react strongly over this harassment. We should not apologise [for Monday's attack on the US embassy] and, if needed, we should close it down," Bashir said.

"It is worth following what happened in Libya. This defamation attacks Allah and his prophet. The punishment is capital punishment [for the movie's producers] no other consideration."

The Islamic Defenders Front, or FPI, whose white-clad paramilitary was at the forefront of the action, has promised another, larger protest soon.

"As long as Obama has not apologised and revoked the movie, we're not afraid of conducting other rallies. We're targeting 10,000 people in an upcoming protest," said the head of FPI's Jakarta chapter, Novel Ba Mu'min.

Other Muslim scholars in Indonesia called for calm after 11 policemen were injured by flying debris, including marbles fired from slingshots, and five hardline protesters were taken into custody during Monday's protest. (With Bloomberg)
