According to the newspaper, the Turkish tanks and troops started to enter Syrian territory from the Oncupinar border gate at 19:00 GMT and the passage continued until the early hours of Sunday morning.
Later on, NTV broadcaster said, citing a military source, that Turkish tanks were backing the offensive of the Free Syrian Army (FSA) armed opposition group on the positions of Kurdish militia in Afrin.
According to the broadcaster, the Turkish military is not facing serious resistance from the Kurdish People's Protection Units (YPG), which is abandoning positions at Syrian-Turkish borders and retreating deeper into the Syrian territory.
However, a spokesman for the YPG in Afrin denied Turkish claims that its forces had entered the district.
Following the airstrike, the authorities of the Afrin canton told Sputnik that at least 10 Afrin residents had been injured in the attack.
According to media reports, during the airstrikes, the Rubar refugee camp for internally displaced persons from the province of Aleppo was damaged. Turkish warplanes also targeted a local airfield, which was used by the US forces for arms deliveries to Kurdish militia.
