The man who became known as the "smiling bomber" for his part in
the Bali bombings last year, has been sentenced to death by firing
Amrozi has said he is "happy to die a martyr"
Amrozi bin Nurhasyim was found guilty of conspiring, planning and carrying out an act of terrorism, which killed 202 people.
He smiled when the guilty verdict was read out and turned around to the courtroom and gave the thumbs-up sign when the judge handed down the death sentence.
Amrozi is the first man to stand trial for the bombs, which ripped through a busy nightclub area in the island's Kuta district on 12 October, killing mostly foreign tourists.
The BBC's Rachel Harvey, who was in court, said the judge announced his verdict in a strong, clear voice.
"Amrozi has been legally and convincingly proven guilty of terrorism," said Chief Judge I Made Karna.
But his final words were almost drowned out by cheers and applause from the relatives and survivors of the bombings.
'Not against Australians'
It could be some time before the death sentence is carried out.
Amrozi's lawyer, Wirawan Adnan, said he would launch an appeal on Friday morning.
He said Amrozi was sorry for the deaths of those people who were not targets.
Citizens from 21 countries died:
"He doesn't have anything personal against the Australians, for instance. The targets were the Americans and the Jews."
Australian Prime Minister John Howard welcomed the verdict and
said his government would not appeal for Indonesia to commute the
"Most of all I hope that this verdict provides some sense of comfort to those who lost their loved ones in this tragedy and that they feel in some way that justice has been done," he said.
The UK's Deputy Prime Minister John Prescott welcomed the conviction and said the government would not object to the death sentence in this case.
"It is not for us to tell other countries what to do," he said.
Amrozi, one of three brothers arrested in connection with the Bali operation, was charged after he admitted buying the explosives and the minivan used in the blasts.
Police said the bombings were planned by Jemaah Islamiah (JI), a militant Muslim group which wants to overthrow the Indonesian Government and set up a Muslim alternative across south-east Asia.
Amrozi, a 41-year-old mechanic, has denied the attack was the work of JI, which has been linked to Osama Bin Laden's al-Qaeda network.
Five judges heard from more than 40 witnesses during Amrozi's trial, including survivors of the attack.
The Australian press nicknamed him the "smiling bomber" after he appeared laughing before television crews following his arrest last year.
'Happy to die'
The other key suspects in the case are on trial separately.
During his trial, which began in May, Amrozi said the Bali bombings had "positive aspects" because they encouraged people to re-embrace religion and weakened the corrupting influence of foreign tourists.
Amrozi has said he is not worried about the death penalty.
"I'll be happy to die a martyr," he said recently. "After me there will be a million more Amrozis."
Indonesian police suspect JI was also behind Tuesday's car bomb attack on the Marriott Hotel in Jakarta, which killed at least 10 people and injured dozens of others.
They said documents found in the possession of JI members arrested last month indicated an attack in the area around the hotel was imminent and police patrols were stepped up.
