Heavy fighting erupted over the weekend near the town of Ras al-Ayn, in northern Syria, where Turkish forces and Syrian government forces engaged in fighting.
Turkey's Defense Ministry says a auto bomb has killed eight people and wounded at least 20 others in a town in northern Syria, which Turkish troops captured.
More than 20 people were wounded in the simultaneous attacks, said the Britain-based monitor said. A small truck exploded outside a bakery there, an emergency worker told Reuters news agency.
On Oct. 22, Turkey and Moscow reached a deal under which YPG/PKK terrorists would pull back 30 kilometers (18.6 miles) south of Turkey's border with Syria, and security forces from Turkey and Russian Federation would mount joint patrols there.
A Turkish cross-border attack against Kurdish fighters on October 9 heightened fears that IS fighters could break out in mass from Kurdish jails.
The offensive faced worldwide criticism over fears that it could undermine efforts to prevent Islamic State re-emerging in Syria and unleash another humanitarian crisis in Syria's eight-year conflict.
YPG was the lead force in the Syrian Democratic Forces (SDF), Washington's main ally in the battle against ISIL in Syria. Ankara, however, has repeatedly threatened to resume the offensive, claiming that the "terrorists" are still present in the border areas.
The recent Turkish operation was aimed at seizing a strip of land roughly 30km deep along the 440-km border between the two countries.
Ankara sees the YPG as the Syrian offshoot of the outlawed Kurdistan Workers' Party (PKK).
Ankara wants YPG/PKK terrorists to withdraw from the region so that a safe zone can be created to pave the way for the safe return of some 2 million refugees.
