A convoy of 30 Turkish military vehicles entered Syria’s northern Idlib province on Sunday, a war monitor reported, according to the Xinhua news agency.
The military convoy carried logistical and military gear, said the Syrian Observatory for Human Rights.
The UK-based watchdog group said 2,980 Turkish military vehicles had entered Idlib since March 5, when Russia and Turkey brokered a cease-fire between the rebels and the Syrian army in Idlib.
Turkey and Russia agreed to the ceasefire, their two leaders said after talks in Moscow, to contain a conflict that has displaced nearly a million people in three months.
Under the agreement Turkish and Russian forces will carry out joint patrols along the M4 highway linking Syria’s east and west and establish a security corridor on either side of it.
Russia and Turkey back opposing sides in Syria’s nine-year conflict, with Moscow supporting President Bashar al-Assad and Turkey backing some rebel groups. Several previous deals to end the fighting in Idlib have collapsed.
Turkey, which has the second largest army in the transatlantic NATO alliance, has funneled troops and equipment into the region in recent weeks to resist the Syrian government forces’ advance and prevent a wave of refugees over its southern border.
Russia also raced to reinforce its troops in Syria by sea and air before the Ankara-Moscow talks.
