The US-backed Syrian Democratic Forces (SDF) have seized 3,400km2 from ISIS near the Syrian-Iraqi border in the framework of their operation against the terrorist group’s cells in eastern Deir Ezzor and southern al-Hasakah.
According to pro-Kurdish sources, the SDF is aiming to clear from ISIS cells the entire area north of the government-held city of al-Bukamal and then to focus on combating the terrorist group in its last remaining strongholds in the Euphrates Valley.
