Poll: Most believe Russia involved in plane crash


More than eight in 10 registered U.S. voters believe Russia is at least indirectly responsible for the downing of a Malaysia Airlines flight last week in Eastern Ukraine, according to a new poll. 

A CNN poll released Monday found 34 percent believe Russia is directly responsible, while 51 percent believe Russia is indirectly responsible for the apparent missile strike. 

Another 11 percent do not believe the country is responsible at all, and 5 percent express no opinion. 

The United States has said there is strong circumstantial evidence that the commercial airliner with 298 people on board was shot down by pro-Russian separatists, which are backed by Moscow. 

The U.S. has stopped short of saying Russia was directly involved in the attack.

On Monday, Obama said costs would increase for Russia if it continues to support the separatists with training and weapons. Obama called on Russian President Vladimir Putin to urge pro-Russian separatists in Ukraine quit tampering with evidence at the crash site and allow unimpeded access by international monitors.

The poll found 80 percent of people believe it is at least somewhat likely that the missile was launched by separatists. 

A total of 71 percent think further economic and diplomatic sanctions should be imposed on Russia if it is found to be responsible for the downing. Only 9 percent support military action, and another 19 percent advocate no action. 

The overwhelming majority, 91 percent, does not trust Russia or the pro-Russian separatists to cooperate fully with the international investigation. The U.N. Security Council, including Russia, passed a resolution Monday calling for an independent investigation and that urged all parties to allow safe access to the crash site. 

The poll surveyed 899 registered voters and has a margin of error of plus or minus 3.5 percent.
