More than 100 Turkish troops armed with thermal rockets and sophisticated weaponry on Tuesday entered the town of Cerablos in the Kurdish region of Kobani.
The contingent of Turkish soldiers reportedly left for their bases after an hour.
A spokesman for the Kurdish militias in the border towns of Kobani and Efrin accused the Turkish forces of supplying arms and ammunition to insurgents fighting Syrian President Bashar al-Assad’s government.
The Turkish foreign ministry has denied reports of cross-border incursion into Syria.
The NBC News also reported on July 31 that nearly two dozen MANPADs (man-portable air-defense systems) have been delivered to the insurgents in Syria by Turkey.
Ankara’s intervention in Syria’s internal affairs has drawn criticism from Turkey’s opposition parties.
The leader of the Republican People’s Party warned the government last month against dragging the country in the “Middle Eastern quagmire” by its aggressive stance against Syria.
