UPDATE:
Unconfirmed description of what has happened per different sources' reports on social media.
TLDR; The two men were taken by the militants from their father while working & later found shot to death with bullets to the head.
"The story that happened in the valley is as follows
10:30 AM
A group of about 20 people in cars, clothes and flags belonging to HTS, it's unknown of course whether they actually belong to HTS or not, stopped 4 people from Jankimrah who were working in Qalatiyah: Thaqib, his sons Issa and Yousef, & a young man named Aghyad.

They asked them about their situation: Aghyad said he is alone and his father is deceased. Thaqeb said he's married and Issa and Youssef are his two children.
The men said if he has two children, that means they served in the military. Thaqeb said they deserted & did not serve.
The men said in any case they'll take them and 'fix their situation' [usually meaning reconciliation for ex-SAA soldiers]
After half an hour, they were found dead at the Kaiyimeh junction with a bullet to the head each."
