WASHINGTON — The U.S. scrambled fighter aircraft Thursday to protect American special operations forces and allies from Syrian government warplane attacks near the northeastern Syrian city of Hassakeh, the Pentagon said Friday.



Navy Capt. Jeff Davis said the U.S. has increased combat air patrols in that area and has warned Syria that America will defend coalition troops. He also said he believes this is the first time the U.S. has scrambled aircraft in response to an incident like this involving Syrian government bombings.



He said a small number of U.S. commandos were in the area training and advising Syrian Democratic Forces. The strikes, he said, "did not directly impact our forces. They were nearby - close enough that it gives us great pause."



The U.S. initially contacted the Russians, and Moscow denied responsibility for the bombings. The U.S. relayed the warning to Syria through Russia because they are allied with the Syrian government in that country's civil war.



Saying the U.S. will do what is needed to protect coalition forces, Davis added, "The Syrian regime would be well advised not to do things that would place them at risk."



The U.S. aircraft arrived as the two Syrian jets were leaving, Davis said, so the U.S. had no radio contact with them. Efforts by Kurdish forces on the ground to contact the Syrian jets were unsuccessful, he said.



Syrian government forces have been bombing Kurdish-controlled portions of Hassakeh in recent days, and scores of residents have fled the city.



The additional U.S. combat air patrols will monitor the situation and provide assistance to coalition forces if needed, but are not enforcing any kind of no-fly zone, Davis said.



President Obama has authorized the deployment of up to 300 U.S. special operations forces to Syria to work with the Syrian Democratic Forces. Small groups have routinely been moving in and out of the country to conduct the training and advising mission.
