伴随着“叙利亚自由军”的日渐衰落与“伊斯兰国”等恐怖组织的崛起，美俄等国先后出兵打击该地区的恐怖主义势力。这些恐怖组织发展过程中，“伊斯兰国”与“支持阵线”两大恐怖组织先后脱离了“基地”组织的控制。规模较小的恐怖组织则试图通过联合的方式增强实力，但未获成功。在国际社会的联合打击下，规模最大的“伊斯兰国”已经失去了叙利亚境内所有主要据点，而仍盘踞在伊德利卜地区的沙姆解放组织也被迫开始“去极端化”。然而，叙利亚的恐怖主义势力仍保留着基本的组织架构和可观的武装力量。该国仍然面临着较为严峻的反恐形势。
With the gradual decline of the “Free Syrian Army” and the rise of the terrorist organizations such as the “Islamic State”，the United States，Russia and other countries have sent troops to combat terrorist forces in the region. During the development of these terrorist organizations，the two major terrorist organizations the “Islamic State” and “Al-Nusra Front” successively broke away from the control of “Al Qaeda”. Smaller terrorist groups have tried unsuccessfully to increase their power through coalitions. Under the joint strikes of the international community，the largest terrorist group “Islamic State” has lost all major strongholds in Syria，and the “Hay’ at Tahrir al-Sham” in Idlib has also been forced to “de-radicalize”. However，the terrorist forces in Syria still retain their basic organizational structure and considerable armed forces. The counter-terrorism situation remains rather severe in the country.
