Russia sent about 300 more military police and more than 20 armoured vehicles to Syria on Friday under an accord between Ankara and Moscow that has halted Turkey's military incursion into northeast Syria.
The deal, sealed on Tuesday by Presidents Tayyip Erdogan and Vladimir Putin, requires that Russian military police and Syrian border guards remove all Kurdish YPG militia from within 30 km (19 miles) of the Turkish border by next Tuesday.
The military police, from the southern Russian region of Chechnya, will help with the withdrawal of Kurdish forces and their weapons to 30 km of the Syrian-Turkish border, Interfax news
