JAKARTA, June 22 (Xinhua) -- An Indonesian court on Friday sentenced to death a radical cleric linked with Islamic State (IS) group for planning and ordering a spate of militant strikes across the country from his jail.

Aman Abdurrahman, 46, known as the ideological leader of Jemaah Ansharut Daulah (JAD), an allegiance of the global IS terrorist group in Indonesia.

"(The court) sentences defendant to death," presiding judge Akhmad Jaini said in a session at the South Jakarta district court.

Abdurrahman alias Oman Rochman or Abu Sulaiman was found guilty of engaging in terrorist acts in the country, according to the panel of judges.

"The defendant is convincingly proven implicating in terrorist strikes," judge Jaini said.

Abdurrahman was convicted of plotting suicide attacks in Jakarta in January 2016, leaving eight people dead, including four attackers, suicide attacks in a bus stop in east Jakarta that killed three police officers, and a church bombing in East Kalimantan of Borneo island that killed a two-year-old girl and wounded four children, the panel said.

Besides, the cleric was found behind the shooting of a police officer in Bima of West Nusa Tenggara province last year and a stab of a policeman in North Sumatra province in the year, it noted.

Abdurrahman had served imprisonment with a maximum security after the strikes in 2016.

The court decision comes as Indonesia seriously beefs up a fight against a rising tide of homegrown militancy marked by the most recent suicide attacks in the country's second largest city of Surabaya and Riau province last month that killed over 30 people, which pushed the lawmakers to pass a tougher anti-terror law.
