News agencies related to the terrorists of the Hayat Tahrir al-Sham group reported that a strike on the convoy was caused by artillery of the Syrian army. These messages, however, did not find evidence.
The Turkish General Staff, as usual, downplayed the losses and stated that their convoy was heading to Aleppo under an agreement on the creation of de-escalation zones. True, it is strange that the Turks decided to execute their part of the agreement almost a year after its signing. And in an incredible way, it coincided with the beginning of a military operation in Syrian Afrin.
Recall that the Turkish command has already threatened to increase its forces in the region before.
