Yara Bayoumi at Reuters reports on the complicated minuet being danced by Russia, the Syrian Air Force, and the United States.
The Syrian Air Force was bombing positions of the Syrian Democratic Forces, a U.S. euphemism for the leftist Kurds of the YPG. The U.S. Air Force shot down the plane (apparently the pilot was able to eject and survive). The U.S. is depending on the Syrian Kurds to take Raqqa city, where they already hold a few neighborhoods. It is the so-called capital of ISIL (ISIS, Daesh). Of all the military forces in the region, only the Kurds have been willing to provide ground forces to roll up ISIL in eastern Syria, with the help of U.S. and coalition air support. If the U.S. proved unable to protect the YPG Kurdish fighters from the regime and from ISIL, they would peel off.
The Kurds are generally considered neutral as between the Bashar al-Assad regime and the mostly Sunni fundamentalist rebels challenging him. The Syrian Kurds want at the least more “states’ rights,” from the regime, but for the moment they enjoy semi-autonomy given that the regime is weak and bogged down in the fight against the rebels. The YPG Kurds have some Arab allies, but most of the fundamentalist Arab militias hate them, partly for being Kurds and partly for being secular leftists.
It is not clear why the Syrian regime chose to bomb the Kurds. It likely fears that the latter are taking over Raqqa province permanently, despite its large Arab population. After ISIL is defeated, Damascus is not going to be sanguine about an expanding Kurdistan that permanently detaches large swathes of Syria from its government. The U.S. military make be sanguine about a Kurdish semi-autonomous zone stretching south from Hasaka all the way down to the borders with Jordan and Iraq. But this development is not acceptable to the Syrian regime.
The development is also not acceptable to Turkey, which has also bombed the Kurds allied with the U.S., despite Turkey being a member of NATO and a U.S. ally. It is possible that Ankara and Damascus are coordinating in hopes of rolling back up the Kurdish fighters as the war winds down and the U.S. becomes restless and leaves.
The problem with the U.S. shooting down that Syrian plane is that the Syrian Air Force is allied with the Russian Federation, and the Russian Aerospace forces often fly alongside the Syrian pilots.
The Russians complain that the U.S. did not warn them before bombing in east Syria, and they should have under the agreement between Washington and Moscow.
And, Russia announced that it would possibly shoot down any U.S. air craft operating in western Syria.
Those are about the most dangerous words I’ve heard in decades, since the era of the Cuban missile crisis or the dark Cold War film Fail Safe (1965).
BBC Monitoring translated a statement of Russian Foreign Minister Sergei Lavrov:
Regarding what is happening “on the ground” in Syria, it is necessary to completely respect the sovereignty and territorial integrity of Syria. So any actions “on the ground” – and there are many participants, including those who conduct military operations – must get Damascus’ approval.

For its part the U.S. military issued a statement saying it has no ambitions in Western Syria, doesn’t intend to fight there, and is not intent on ousting Bashar al-Assad:
