DAMASCUS, June 15 (Xinhua) -- The Turkish forces brought in military units to observation points it maintains in northern Syria on Saturday, a war monitor reported.
A total of 35 military vehicles entered early on Saturday the Syrian territory in the countryside of Idlib and Hama provinces, the Syrian Observatory for Human Rights said.
The new deployment comes two weeks after the Turkish side deployed troops to the observation points in Hama and Idlib countryside.
The development comes a day after Turkish reports said that Syrian troops attacked a Turkish observation point in Idlib.
It's worth noting that the Turkish forces maintain several observation points in Idlib, as this province, as well as rebel-held areas in the surrounding of Idlib such as in Latakia and Hama as well as Aleppo countryside areas, are included in a de-escalation zones' deal.
The de-escalation zones' deal was reached between Russia and Turkey in last September.
Under the deal, the ultra-radical groups should evacuate their areas and hand over their heavy weapons.
However, the al-Qaida-linked militant groups expanded and captured the entire Idlib area and engaged in battles with the Syrian Army and these battles evolved into a full showdown that has started in late April.
