Answer: Syria
Notes: Aleppo, Syria's second-largest city, has been overtaken by Islamist rebel factions for the first time in over a decade. Located in northern Syria, about 30 miles from the Turkish border, Aleppo is a significant ancient trade hub. The Quwayq River runs through Aleppo, often drying up due to heavy water usage in Turkey. The terrorist group Hayat Tahrir al-Sham (HTS) is involved in the takeover. Aleppo is home to the UNESCO World Heritage site "Old City of Aleppo," known for its medieval Islamic architecture, including the iconic citadel.
