Prosecutors are seeking the death sentence for Indonesian radical Islamic cleric Aman Abdurrahman for inciting others to commit various terror attacks in Indonesia, including an attack in Jakarta in 2016 that left four bystanders dead.
Abdurrahman - considered the de facto head of all IS supporters in Indonesia - is also the spiritual leader of local extremist network Jamaah Ansharut Daulah (JAD).
He sat silently as the prosecution announced the sentencing demand today before a panel of five judges.
Prosecution lawyer Anita Dewayani said Abdurrahman's acts had resulted in deaths and injuries and there was no reason for lenience.
Prosecutors also said on Friday that they arrived at the recommendation of a death penalty after hearing the various witnesses' testimonies and checked other evidence that were presented in court throughout the trial that started on Feb 15.

Suicide bombings Sunday and Monday in Surabaya, Indonesia's second-largest city, killed 26 people, including 13 attackers.
They also have said that Abdurrahman was behind a suicide attack past year that left three police officers dead at a Jakarta bus station, the bombing of a church in Samarinda on Borneo Island that wounded four children and the bombings in Thamrin Kampung Melayu. Two families carried out the attacks, using children as young as 7.
He was sentenced to prison in 2004 after a bomb prematurely exploded at a house in West Java, and again in 2011 for his role in helping set up a jihadi training camp in a mountainous area of Aceh province. Abdurrahman is accused of being the key ideologue for IS militants in Indonesia and ordering attacks including a January 2016 suicide bombing and gun attack in the capital Jakarta that killed four civilians and four attackers.
