Obama pledges 'any assistance we can'

At the top of an infrastructure speech in Delaware Thursday, President Obama offered "any assistance we can" with the investigation into a crashed passenger airline near the Ukraine-Russia border.

"Obviously, the world is watching reports of a downed passenger jet near the Russia-Ukraine border," Obama said. "It looks like it may be a terrible tragedy."


The president said he had directed his national security team to "stay in close contact" with Ukrainian authorities investigating the crash, and offered U.S. aid "to help to determine what happened and why."

Malaysia Airlines Flight 17, a Boeing 777 traveling from Amsterdam to Kuala Lampur, had 280 passengers and 15 crew members on board. Ukrainian authorities have accused pro-Russian separatists battling government forces in the country's eastern regions of shooting down the plane, although the U.S. has said it cannot confirm reports on the cause of the crash.

The president said the nation's "first priority" was "working to determine whether or not there were American citizens on board."

"Our thoughts and prayers are with all the families of the passengers, wherever they call home," Obama added.
