Both pro-Russian rebels and the Ukrainian government forces are denying any responsibility for downing the Malaysia Airlines jetliner carrying 295 passengers and crew. Multiple reports state the Boeing 777, traveling from Amsterdam to Kuala Lumpur, appeared to have broken up before impact, with the burning wreckage scattered over a wide area. All passengers are believed to have died.
At a press event in Delaware, President Obama said he has directed national security advisors to stay close contact with the Ukrainian government. Reuters reports that just yesterday, the U.S. administration tightened its sanctions against Russia over the ongoing fighting in Ukraine. Shortly thereafter, Ukraine claimed that Russian had downed one of its war planes.
