An Indonesian court on Monday sentenced an Islamic extremist to eight years in jail for possession of firearms and explosives, but left out a charge of plotting to attack the Danish Embassy.

Heri Sigo Samboja, alias Sogir, 28, was found to be guilty of an "evil conspiracy," chief judge Mirdin Alamsyah told a Jakarta district court. "The defendant is found guilty of committing a terror act and sentenced to eight years in prison," he said.

The sentence was lighter than the 12 years sought by prosecutors, who had also charged Samboja with plotting to attack the Danish Embassy in Jakarta in revenge for cartoons of the Prophet Mohammed published in a Danish newspaper in 2005. Alamsyah however did not mention the charge and gave no reason for the omission.

Samboja is one of more than 100 people detained after the discovery of a militant training camp in Aceh province, Sumatra, in February. The camp allegedly included militants from various regional groups, including some with links to Al Qaeda, under the leadership of Indonesian terror mastermind Dulmatin, who was killed by police in March.
