Judge Lexy Mamoto said 36-year-old Maulana Yusuf Wibisono, alias Kholis, was guilty of committing acts of terror and acting in a leadership role in the Jemaah Islamiyah (JI) network.

'The defendant was proven convincingly to have carried out acts of terror and has been sentenced to ten years' imprisonment,' Judge Mamoto said, reading out the verdict.

Judge Mamoto said Wibisono 'created social and political disturbance and damaged the country's image', but had shown remorse and been cooperative during his trial.

He said Wibisono had been the branch leader of a military wing within JI that was led by Abu Dujana, currently also on trial.

Wibisono had arranged the transfer of 100 kilograms of TNT to the restive Poso region on Sulawesi island and had undergone military training in different locations on Java island with several other men.

In a separate trial, Judge Makmun Masduki handed down a 10-year jail sentence to 40-year-old Sarwo Edi, who was also a branch leader of a military wing within the JI network.

Judge Masduki said that Edi was an instructor in armed training exercises in Java and arranged the transfer of explosives and weapons to Poso.

The court later in the day also handed down 10-year terms to three others, and eight years to one more for involvement in the transfer of explosives and weapons to Poso.

Poso has seen sporadic unrest between Muslims and Christians since trouble flared in 2000 and 2001, killing around 1,000 people.

JI was previously said to have links with Al-Qaeda, but security analysts now believe the organisation is isolated. -- AFP
