At least 18 civilians have been killed and 30 injured by a vehicle bombing in opposition-held western Aleppo Province in northern Syria.
The Turkish military said Saturday that the explosion was near the bus terminal, damaging buildings and setting cars alight.
The Turkish Defense Ministry condemned the attack, blaming the Kurdish militia YPG “using the same methods as DAESH [the Islamic State]”.
Turkish-supported Syrian rebels pushed ISIS out of al-Bab in February 2017, and the opposition has continued to hold the town despite Russia and the Assad regime reoccupying all of Aleppo city and other parts of Aleppo Province.
Al-Bab is 40 km (25 miles) northeast of Aleppo city, 30 km (19 miles) south of the Turkish border, and about 50 km (30 miles) west of Manbij, the western-most point of Kurdish-held territory.
Turkey has been pressing for the withdrawal of the YPG-led Syrian Democratic Forces from Manbij, declaring that the YPG are part of the Turkish Kurdish insurgency PKK.
On October 22, Turkish President Recep Tayyip Erdoğan and Russian counterpart Vladimir Putin announced an agreement for joint Turkish-Russian military oversight of a zone 480 km (270 miles) and 30 km (19 miles) deep across two Kurdish cantons in northeast Syria. Erdoğan repeated his demand for YPG departure from Manbij.
Earlier this month the border city of Tel Abyad was twice struck by vehicle bombs, killing 21 civilians and wounding more than 50.
