The monitoring had not yet begun, but the forces would report to senior US commanders, Sharvan Kobani told Reuters after meeting US military officials in the town of Darbasiya next to the Turkish border.
The officials had toured Darbasiya which was hit by Turkish artillery fire earlier in the week.
Turkish warplanes carried out air strikes against Kurdish militants in northeastern Syria and Iraq’s Sinjar region on Tuesday in an unprecedented bombardment of groups linked to the PKK, which is fighting an insurgency against Ankara in Turkey’s southeast.
Those attacks killed nearly 30 YPG fighters and officials, a monitoring group reported.
Since Tuesday the YPG and Turkish forces have traded artillery fire along the Syria-Turkey border.
Turkey’s bombardment of YPG positions complicates the US-backed fight against Islamic State in Syria, where the YPG has been a crucial partner on the ground for Washington.
The YPG is a key component of the Syria Democratic Forces (SDF), a US-backed alliance and Kurdish fighting groups involved in a campaign to drive Islamic State out of its Syria stronghold, Raqqa.
US Nato ally Turkey views the YPG and other PKK-affiliated groups as terrorists. Pentagon spokesman Captain Jeff Davis said yesterday US troops were deployed along the border.
“We continue to urge all the parties involved to focus on the common enemy which is ISIS (Islamic State),” he told reporters.
Hundreds of US troops are deployed on the ground in Syria to support the Raqqa offensive.
Meanwhile, fierce clashes between militants and Islamist rebels near Damascus left at least 40 dead and 70 wounded, a monitoring group said.
The Syrian Observatory for Human Rights said the clashes pitted the rebel faction Jaish al-Islam against Fateh al-Sham, Al Qaeda’s former branch in Syria, and Faylaq al-Rahman.
“There were at least 15 dead among the ranks of Jaish al-Islam and 23 among its adversaries” as well as two civilians, the Britain-based Observatory said. Another 70 were wounded.
Jaish al-Islam said its opponents had provoked the clashes by harassing reinforcements headed for Qabun, east of the Syrian capital, a front with regime forces. Faylaq al-Rahman denied the allegation.
