(Washington, DC)  --  Senator John McCain says there will be "hell to pay" if it turns out that Russia or Russian separatists were involved in the crash of a Malaysian airliner in eastern Ukraine. 

The Arizona Republican made the comment on MSNBC.  He also warned that no one should yet jump to conclusions about what happened.  Ukrainian officials claim the Boeing 777 was brought down by a ground-to-air missile. 

Around 280 passengers and 15 crew members are presumed to be dead.
