In a major shift in Syria's civil war, Islamist insurgents led by Hayat Tahrir al-Sham captured Hama and are moving towards Homs. Thousands are displaced as the Syrian military conducts a tactical withdrawal. Turkey monitors the situation closely, considering its implications for border security and Kurdish forces. Despite denying involvement, analysts suggest Turkey's indirect support has facilitated the offensive, raising fears of destabilization in the region and a potential influx of refugees. Meanwhile, Iran and Russia's positions remain uncertain as the insurgents threaten to challenge Assad's regime.
