Russia strikes US-backed rebels in Syria -US official
Russia carried out air strikes on Thursday in southern Syria against rebels battling Islamic State, including forces backed by the United States, a senior US defense official said, adding Washington would raise the matter with Moscow.
The official, who spoke on condition of anonymity, strongly criticized the Russian strikes near al-Tanf, noting that no Russia or Syrian ground forces were in the area at the time -- effectively ruling out an argument of self-defense.
"Russia's latest actions raise serious concern about Russian intentions," the official said.
