WASHINGTON — Senior U.S. intelligence officials said Tuesday that Russia was responsible for "creating the conditions" that led to the shooting down of Malaysia Airlines Flight 17, but they offered no evidence of direct Russian government involvement.
The intelligence officials were cautious in their assessment, noting that while the Russians have been arming separatists in eastern Ukraine, the U.S. had no direct evidence that the missile used to shoot down the passenger jet came from Russia.
The officials briefed reporters Tuesday under ground rules that their names not be used in discussing intelligence related to last week's air disaster, which killed 298 people.
However, the officials said they did not know who fired the missile or whether any Russian operatives were present at the missile launch. They were not certain that the missile crew was trained in Russia, although they described a stepped-up campaign in recent weeks by Russia to arm and train the rebels, which they say has continued even after the downing of the commercial jetliner.
In terms of who fired the missile, "we don't know a name, we don't know a rank and we're not even 100 percent sure of a nationality," one official said, adding at another point, "There is not going to be a Perry Mason moment here."
