No, this isn't the same convoy that was spotted some days ago. I see from the following report that the bad guys, now clearly aware that the earlier convoy was spotted, are trying subterfuges to shake off the observers.
I should add that the very last sentence in the report conflicts somewhat with a few of its earlier statements. This leads me to wonder whether these chemicals-transporting convoys are being helped by the Turkish military, or whether the military is trying to stop them. Maybe the tie-breaker is that the military is now trying to stop such convoys after being caught red-handed facilitating the previous shipment. But that's just a guess based on very limited information. The fog of war is getting thicker than pea soup.
It went on to say that the chemicals would go through Ariha town under tight security measures of Tahrir al-Sham. The White Helmets were also called for help by Tahrir al-Sham in several regions of Idlib concurrent with the arrival of the chemicals in Jisr al-Shughour.
In a relevant development earlier this month, the White Helmets had sent chemicals for the Turkistani Islamic Party in Jisr al-Shughour in Northeastern Idlib.
Irregular movements by the White Helmets have been recently spotted in a large triangular region from the Turkish borderline to Jisr al-Shughour and the borders with Lattakia in West, the media outlet reported, adding that Tahrir al-Sham and White Helmets are preparing to launch a fake chemical attack in Idlib to later accuse the Damascus forces.
Media sources reported earlier this month that the Turkish army sent several trucks carrying chlorine to the Ankara-backed terrorists' stronghold in Idlib, adding that a number of commanders of militant groups left the region.
The Arabic-language website of Sputnik news agency quoted local sources in Idlib province as saying that a Turkish military convoy, consisting of tens of trucks, and accompanied by Tahrir al-Sham terrorists, entered Syria through Kafr Lousin passageway in Northern Idlib and were transferred to the region under the supervision of Turkey in Jisr al-Shughour in Western Idlib and Northwestern Hama.
They added that 8 trucks carrying plastic barrels containing fluid Chlorine were unloaded in one of the bases of Turkistani terrorist group in the village of Halouz in Western Jisr al-Shughour.
Also, 18 other trucks, carrying prefabricated residential boxes, cement walls and other technical equipment, communication systems and electronic sniper guns, were transferred to Jabal Ishtabraq region.
The sources also said that 3 trucks moved towards Turkey at night under heavy security measures of Tahrir al-Sham Hay'at, raising the speculations that they had transferred the foreign terrorist commanders of Tahrir al-Sham to Turkey.
Meantime, the Turkish forces stopped activities of al-Barqoum checkpoint which was the biggest Tahrir al-Sham checkpoint in Aleppo-Damascus highway.
