A U.S. army convoy entered Hasakah city and deployed around the Sinai prison in the Zuhur neighborhood south of the city between 9:46 PM and 10:15 PM UTC on January 19, 2026, according to X posts by mintelworld and BarracudaVol1, as the YPG issued statements vowing to defend the Rojava Revolution through a revolutionary people's war. The YPG declared on X that they are the People's Protection Units defending their people and will protect Rojava gains against what they described as a genocide concept carried out for two weeks, urging all relevant parties to mobilize in support, per posts by YPGinfo. Kurds in Qamishli placed themselves on high alert and ready to resist, according to NebilYousif on X, while SDF/YPG sympathizers in Qamishli walked toward Nusaybin to open the border gate, as reported by BarracudaVol1 on X. An X post by hakikatsizler stated that the allegiance of the Sarranid, armed wing of the Shammar tribe, remains with the USA and remains unconfirmed whether they have switched sides. Linashamy shared details from an interview with Al Jazeera English on defections among SDF ranks and a popular movement against SDF practices due to discrimination and repression in areas west of the Euphrates. These developments follow Syrian army advances into Hasakah city center and SDF declarations of breaking with Damascus reported earlier on January 19, according to previous reports citing X posts by BarracudaVol1 and QalaatAlMudiq.
