Krayem, 32, faced the court in Stockholm for his actions related to the heinous crime that shocked the world when a video emerged showing the death of Lt. al-Kasasbeh. Captured after his plane crashed in Syria during a mission against ISIS, the pilot's fate sparked outrage in Jordan and beyond. Witness accounts and evidence presented in court indicated that Krayem had a direct role in the execution, as he was present at the scene, armed, and recorded by media during the event.

Judge Anna Liljenberg Gullesjo expressed the severity of the crime, stating that Krayem's involvement went beyond mere presence; he was a key figure who helped facilitate the execution. While it was determined that the actual fire was ignited by another man, Krayem's actions warranted his classification as a perpetrator. Alongside the life sentence for these serious war crimes, the judge ordered that Lt. al-Kasasbeh's family be compensated approximately 80,000 Swedish kronor (around $8,200).

Krayem's past includes a 30-year sentence for participation in the deadly Paris attacks in November 2015 and involvement in the Brussels bombings in March 2016. His criminal background and connection to extremist groups illustrate a persistent threat that authorities in Sweden and other European countries continue to address in the face of rising terrorism since the conflicts in Syria and Iraq involving ISIS emerged. Lt. al-Kasasbeh's execution has left a lasting impact on Jordan, where his family is thankful that justice is being served, despite the emotional toll of revisiting such a tragic event.
