The verdict against the 32-year-old from Malmö is the first in the world where someone is convicted for involvement in IS's murder of Muath al-Kasasbeh, who was taken captive after his plane crashed over Syria on Christmas Eve 2014.
My clients are extremely grateful for the work that Swedish authorities have carried out, says lawyer Mikael Westerlund who has represented the pilot's parents and siblings.
Maximum sentence
They welcome that Krayem is sentenced to the maximum sentence of life imprisonment, and that he is convicted of both gross war crime and terrorist crime, says Westerlund.
My clients think it has been important that he is convicted of terrorist crime, first and foremost they see him as a terrorist.
The relatives had during the trial hoped to get answers on where the remains of their son and brother may be, he says.
Their greatest wish is to get the remains home to be able to bury him. But based on the information that has emerged during the main proceedings, we can conclude that they will never get the remains home. It is clear that it is extremely difficult to handle.
Analyze the verdict
Osama Krayem has admitted that he was at the scene at the time of the murder, but denies being involved. His lawyer Petra Eklund says that they will analyze the verdict before making a decision on whether it will be appealed or not.
Prosecutor Henrik Olin is satisfied with the verdict.
It feels satisfying that the district court essentially fully approves the prosecution in all parts. Both when it comes to the question of whether the man should be considered a perpetrator, that he should be convicted of both gross war crime and terrorist crime and that he should be sentenced to a Swedish life sentence as well.
Krayem has previously been sentenced to prison for terrorist crimes in France and Belgium, to 30 years and life respectively. When the Swedish legal process is completed, he will be returned to France.
