In the complex mosaic of the new Syria, the old battle against the group calling itself Islamic State (IS) continues in the Kurdish-controlled north-east. It's a conflict that has slipped from the headlines - with bigger wars elsewhere.
But Kurdish counter-terrorism officials have told the BBC that IS cells in Syria are regrouping and increasing their attacks.
Walid Abdul-Basit Sheikh Mousa was obsessed with motorbikes and finally managed to buy one in January. The 21-year-old only had a few weeks to enjoy it. He was killed in February fighting against IS in north-eastern Syria.
Generations of his extended family gathered in the yard of their home in the city of Qamishli to tell us about his short life. I see him everywhere, said his mother, Rojin Mohammed. He left me with so many memories. He was very caring and affectionate.
Kurdish authorities are grappling with the resurgence of IS threats as they hold around 8,000 suspected IS fighters from 48 countries in a network of prisons in the north east. The largest jail for IS suspects is al-Sina in the city of Al Hasakah.
Some detainees, wearing disposable masks to prevent infection, remain locked away indefinitely with tuberculosis as a constant companion. A former IS fighter, Hamza Parvez from London, expressed his fears for his life in prison, challenging notions of risk as he pleads for his return to the UK.
The situation is dire not only for fighters but also for their families, who are imprisoned in sprawling tented camps. These camps, like Roj and al-Hol, have been described as open-air prisons where support from human rights organizations is scarce and conditions are harsh.
As Kurdish authorities face these challenges, IS continues to find ways to recruit and strengthen its hold within the regions, raising the alarm for all stakeholders involved in the fight against terrorism in the Middle East.
