A third key suspect in last year's Bali bombings has been found guilty by an Indonesian court.
Ali Imron has repeatedly said he is sorry for his actions
Ali Imron, a 33-year-old Islamic teacher, was convicted of planning an act of terrorism which killed more than 200 people.
He was sentenced to life in prison. He could have faced the death penalty, but the court said it had taken into account Ali Imron's expression of regret.
The BBC's Rachel Harvey said Ali Imron, clean shaven and wearing a dark suit, sat almost motionless as the verdict was delivered.

Two other men, including Ali Imron's brother Amrozi, have already been convicted and sentenced to death for their part in the Bali conspiracy.
Ali Imron had admitted to helping assemble one of the bombs which exploded in Bali on 12 October and driving a bomb-laden minivan to the site of the attack.

The defendant had committed "an extraordinary crime
and a crime against humanity", the judge said.
What has set him apart from the other key suspects has been his expressions of remorse.
Judge Mulyani said Ali Imron "had felt guilt and has honestly

Unlike the others, he has made no angry gestures or criticisms of the US, and has urged people not to follow in his footsteps.
For this reason, the prosecution had only asked for a sentence of 20 years in prison, rather than the maximum penalty of death.
More than 30 people have been arrested in connection with the Bali attacks, although most of those are suspected of playing minor, supporting roles.
About half a dozen, including the three now sentenced, are believed to have been major players.
The next verdict due, on 2 October, is for Mukhlas, another brother of Ali Imron.
He is accused of masterminding the operation.
The Bali attack has been widely blamed on the Jemaah Islamiah militant group, which wants to create a pan-South East Asian Muslim state.
Its alleged operations chief, Hambali, was arrested in central Thailand last month. He is being interrogated by the US at a secret location.
