The West Jakarta Court sentenced two men to five years in prison in connection with the April 2011 suicide bombing of a police station in Cirebon, West Java.

Yadi Supriadi and Nanang Irawan were found guilty of teaching suicide bomber M. Syarif how to make a bomb. Yadi had previously urged Muslims to wage war against the nation's enemies of Islam during Koran recitation classes, telling listeners that they should make a bomb.

"Yadi has been convincingly proven to be guilty of committing [acts of] terrorism," presiding judge Haswandi said. Both men have been convicted to teaching Syarif how to make a bomb.

On April 15, 2011, Syarif died in a suicide bombing of the Adz-Dzikra mosque inside the Cirebon police headquarters. Thirty-one people were injured in the blast, which killed Syarif.

The defense argued that Yadi only taught Syarif about hating so-called enemies of Islam, not how to make a bomb. The judge rejected the claim, saying that there was evidence that Yadi told his followers how to make a bomb.

"How could we say that the [training] efforts are not related to terrorism," Haswandi said.

Yadi's lawyer Asludin Hatjani said that he had not decided whether his client would file n appeal. Asludin said that he still believed that Yadi was not involved in the suicide bombing.

"M. Syarif was in a group with [Yadi and Nanang], but the suicide bombing in Cirebon was done without Yadi and Nanang's consent," Asludin said, explaining that no one else knew of Syarif's plans.
