Around 450 militants from the Hayat Tahrir al-Sham (HTS) armed group, a re-branded Jabhat al-Nusra (the Syrian branch of Al-Qaeda), arrived in Ukraine on 8 March to fight against the Russian army.
The militants reportedly left Idlib governorate in northern Syria only three days ago, entering Ukraine after passing through Turkey.
The militants consist of both Arab and foreign nationals, as HTS, ISIS, and other militias in Syria allow foreigners to join their ranks.
The newly arrived fighters in Ukraine reportedly consist of approximately 300 Syrians, with the rest a mix of Belgian, French, Chechen, Chinese, Tunisian, British, and Moroccan nationals.
Family members of the militants reported to Sputnik News that high-ranking HTS fighters are coordinating with senior leaders of the Turkistan Islamic Party group, Ansar al-Tawhid, and Hurras al-Din groups, to facilitate the passage of fighters from Idlib to Turkey and then on to Ukraine.
The sources explained further that many of those who have gone to Ukraine are veterans of the US-backed war against the Syrian government and were offered this new task as a means of resolving disputes between the soldiers and the HTS leadership.
The income for Syrian fighters is reported to be around $1,200-$1,500. The income for foreign nationals is not yet known.
