Only Border Syrian Regime Still Controls is with Lebanon

Since extremists from the Islamic State group (IS) seized Syria's al-Tanaf crossing with Iraq, the Syrian regime has effectively lost control of all of its borders except those with Lebanon.

Of Syria's 19 border posts with Lebanon, Jordan, Iraq, and Turkey, government forces now control just seven -- five with Lebanon, and two more, both closed, with Turkey.

Four crossings are controlled by Kurdish forces, four by IS, and another four by al-Qaida's Syrian affiliate or rebels. Opposition fighters also control an unofficial border point with Israel.

- Border with Turkey (9) -

- Kasab: in the western province of Latakia. Under regime control but closed by Turkey since fierce clashes in 2014 between the army and Islamist rebels, who briefly overran the post.

- Bab al-Hawa: Held by Islamist rebels, including Syria's al-Qaida branch Al-Nusra Front. In the northwestern province of Idlib.

- Bab al-Salama: In the town of Aazaz in northern Aleppo province. Held by Islamist rebels.

- Tal Abyad: Held by IS in northern Raqa province, which is almost entirely held by the group. 

- Ain al-Arab: In Aleppo province. Controlled by Kurdish fighters.

- Ras al-Ain: In the northeastern province of Hasakeh. Was the site of ferocious fighting between IS and Kurdish fighters before the latter forced the jihadists out of the post and nearby town.
