Escalating tension continues between the U.S. and Russian over Russian airstrikes that government officials feel are serving to strengthen Syrian President Bashar Assad by targeting “moderate” rebels rather than ISIS fighters that it promised to attack.

The Pentagon is wrestling with the question as to whether the U.S. should use military force to protect U.S. trained and equipped Syrian rebels now that they may be the targets of Russian airstrikes. Pentagon leaders have been consistent in saying that the U.S. must take steps to protect the American-trained rebels.
An international coalition is urging Russia to immediately cease attacks on the Syrian opposition and civilians and focus instead on fighting the ISIS terrorist group.

“We express our deep concern with regard to the Russian military build-up in Syria and especially the attacks by the Russian Air Force on Hama, Homs and Idlib since yesterday which led to civilian casualties and did not target Da’esh,” said the statement, jointly issued late Thursday by the United States, the United Kingdom, Turkey, France, Germany, Qatar and Saudi Arabia.

Russia’s defense ministry said that over the past 24 hours it had damaged or destroyed 12 targets in Syria belonging to the ISIS fighters, including a command center and ammunition depots. A U.S. military spokesman in Baghdad, Col. Steve Warren, said he had no indication that the Russians had hit Islamic State targets.

Concerns are being raised that this conflict is leading to a new alliance between Russia, Syria, Iraq and Iran.
