In response, "Russia's ground and air defenses will track any air targets, including the global coalition's planes and drones, found to the west of the Euphrates River", the ministry said, adding that it is halting the so-called deconfliction coordination with the US aimed at averting air incidents.
The Pentagon issued a statement: "The coalition does not seek to fight Syrian regime, Russian, or pro-regime forces partnered with them, but will not hesitate to defend coalition or partner forces from any threat".
The Russian Defense Ministry said in a statement that as of Monday, all coalition jets and drones flying west of the Euphrates River will be tracked as potential targets.

The US military later said it was seeking to re-establish the hotline.
It also raised questions about how U.S. President Donald Trump's administration, which had previously put Iran "on notice" for its ballistic missile tests, will respond.
The Syrian government forces' march toward the Jordanian border comes two weeks after they reached the border with Iraq for the first time in years.
What the recent incidents "indicate is a complicated and complex battlespace, and we continue to try to operate transparently and to communicate intentions around our actions so it is clear we are focusing on the defeat of ISIS in Syria", US Central Command spokesman Colonel John Thomas said on Monday.
