An Indonesian court has jailed three Muslim extremists to between seven and nine years over a suicide bomb attack on a police mosque last April.
The three men were convicted under anti-terrorism laws for helping orchestrate the attack in Cirebon, western Java, which injured 30 people, mostly police during a prayer service.
The 32-year-old bomber died in the blast.
The judge handed his younger brother Achmad Basuki a nine-year jail term for helping plan the attack, destroying evidence, possessing ammunition and preparing explosives.
"The defendant was proved to have committed offences... under the 2003 law against terrorism," judge Syamsul Bahri told the Tangerang district court.
"The defendant's actions do not support government efforts to combat criminal acts of terrorism."
Tried separately, Arief Budiman and Mardiansyah were both sentenced to seven years for obtaining and selling ammunition.
Prosecutors had requested a 10-year sentence for all three men.
The same court last week sentenced 10 men from Cirebon over the attack.
The April blast left nails, nuts and bolts lodged in people's bodies in the first suicide mosque bombing in the world's largest Muslim-majority nation of 240 million people.
Indonesia is struggling to deal with the threat of homegrown Islamist militants who oppose the country's secular, democratic system and want to create an Islamic caliphate across much of Southeast Asia.
The government and anti-terror police have significantly weakened sophisticated networks, such as al-Qaeda-linked Jemaah Islamiah, responsible for the 2002 Bali bombings that killed 202 people.
