A Syrian-Swedish dual national died after being detained and tortured for several months by the Syrian Democratic Forces (SDF) in the northeastern city of Qamishli, according to the Syrian Network for Human Rights (SNHR).
Alaa Adnan al-Amin was detained by SDF forces following a raid on his home on 20 October,
Following his arrest and detention without charge, al-Amin's family were given no information about his whereabouts or condition.
The SNHR said the family contacted several SDF-affiliated departments within Hasakah governorate to find out information on their relative, to no avail.
Al-Amin's family received a call on 8 March telling them to collect his body from the Al-Hasakah Hospital. The body bore signs of severe torture, including bruising on his chest and legs, swelling, and holes and fractures in his head and rib cage.
The coroner concluded that Al-Amin likely died in January 2026.
On Tuesday evening, a mourning tent erected for family and friends of the deceased was burnt down, reportedly by members of the Revolutionary Youth - a group affiliated with the Democratic Union Party (PYD).
Sources from al-Amin's family said an armed group attacked the family home during a mourning ceremony and set fire to the tent, with machine gun fire heard in the background.
The bereaved family had been calling for an independent investigation into the death and for accountability, which local sources said was the underlying cause of tensions in the area.
The Autonomous Administration in North and East Syria's (AANES) Internal Security Forces, known as the Asayish, said in a statement that "a high-level investigative committee, comprised of specialists and legal experts, has been formed to examine the details of the incident and determine the circumstances of the death".
"The results of the investigation will be published transparently as soon as it is completed, with an emphasis on holding accountable anyone found to be involved in negligence or violations of regulations and laws," the statement added.
However, Al-Amin's forced disappearance and killing is not the only case that has been raised in recent days.
The Kurdish Network for Human Rights in Syria reported that Dutch resident Jwan Sarhan Mahmoud was abducted and forcibly disappeared in Qamishli days after arriving in the region in early 2025.
The network accused a military patrol affiliated with the Kurdish Autonomous Administration of being behind Mahmoud's disappearance.
According to the rights group, Mahmoud arrived in Iraqi Kurdistan in early January 2025 and later entered Qamishli on 6 January, accompanied by individuals involved in recruiting fighters. Mahmoud was himself seeking to join the SDF, according to the network.
After a week without contact with his family, Mahmoud was brought to a relative's home on 13 January 2025 in an Autonomous Administration vehicle. The relatives were informed that the patrol would return to pick Mahmoud up in two hours.
An armed patrol later returned to the house and forcibly took Mahmoud to an undisclosed location - marking the last time his family saw him.
According to information from local lawyers, Mahmoud may be in detention at Qamishli's Alaya prison.
The Kurdish Network for Human Rights has demanded immediate disclosure on Mahmoud's whereabouts, holding the Autonomous Administration fully responsible for his welfare.
