The government of Russia said on Tuesday "it will not allow" that Turkish and Syrian forces fight each other.
"That would simply be unacceptable," said Russian Special Envoy for Syria, Alexander Lavrentyev, during a visit to the United Arab Emirates. "And that is why we will of course not allow it."
The risk of collisions between the two countries has increased since the Kurds in Northeast Syria asked the government of Syrian President Bashar Al Assad for help after the Turkish invasion of the area.
Lavrentyev also described the Turkish invasion of Syria, which began last week, as "unacceptable". The raid took place after the US withdrew its soldiers from the area. Turkey wants to create a 'safe zone' in the border area, to fight terrorism, push back the Kurds and repatriate Syrian refugees.
Kurds asked Syria for help
The Syrian Democratic Armed Forces (SDF), a coalition of predominantly Kurdish militias, requested assistance from the Assad government in exchange for control over Manbij and Kobani. The Syrian government army then steamed to the northeast.
According to the Russian Ministry of Defense, government troops have secured an area of 1,000 square kilometers around Manbij.
Russian soldiers patrol Turkey and Syria
Russia is Assad's most important ally. He only managed to gain the upper hand in the fight against various rebel groups thanks to the military support of the Kremlin. Russian troops have been stationed in Syria since 2015.
The Russian Ministry of Defense announced on Tuesday that Russian soldiers are carrying out patrols in the "no man's land" between Turkish and Syrian troops.
