In a remarkable raid, two Turkish soldiers were taken captive by ISIS militants on the outskirts of al-Bab earlier today. Although details are vague, the Turkish troops were embedded with Syrian rebels fighting under the banner of the Free Syrian Army (FSA).

The incident took place near the village of Dana (northwest of Al-Bab) and was first alleged by Amaq Agency on Tuesday afternoon but later confirmed by Ankara. According to Turkey's Ministry of National Defence, the Turkish Armed Forces have "lost contact" with the two soldiers who's fate is now in the hands of the Islamic State.

At least 17 Turkish soldiers have been killed during operation 'Euphrates Shield', a rebel offensive which has seized large swaths of territory along the Turkish-Syrian border from ISIS and the US-backed Syrian Democratic Forces (SDF).

Yesterday, the Syrian Arab Army (SAA) also conducted a major push en route to Al-Bab, an Islamic State stronghold which is now threatened by several belligerents.
