A hunt for wreckage and evidence is underway in eastern Ukraine Friday after a Malaysia Airlines jetliner with 298 passengers was shot down.
U.S. intelligence authorities said a surface-to-air missile brought down Malaysia Airlines Flight 17 Thursday as it flew from Amsterdam to Kuala Lumpur, but could not say who fired it.
The Ukraine government in Kiev, the separatist pro-Russia rebels they are fighting and the Russia government that Ukraine accuses of supporting the rebels all deny shooting the passenger plane down. Moscow also denies backing the rebels.
Bodies, debris and burning wreckage of the Boeing 777 were strewn over a field near the rebel-held village of Hrabove in the Donetsk region of eastern Ukraine, about 40 kilometers (25 miles) from the Russian border, where fighting has raged for months.

"It'll certainly slow things down in several areas of applied research," he says of the AIDS researchers and experts killed aboard MH17.
"It's hard to comment on lunacy."

"To hear that these folks, who were giants in the field, were lost in such a tragic way on their way to the International AIDS Conference is an incalculable loss."
He says HIV/AIDS researchers are a "resilient group" and they will carry on the torch.
The conferences are generally a time of reflection on the lives lost and continue to be lost to AIDS.
"To have this happen only compounds the sense of loss that many cope with at this event."

Nearly half of those aboard Malaysia Airlines flight 17 were Dutch citizens.
And on Monday, the Dutch Embassy in D.C. will open its doors to members of the public who want to share their condolences, with a condolence register available to sign.
Staff at the embassy plans to hold a moment of silence for the victims.

The airspace over the disputed territory in the eastern Ukraine is now closed and all commercial flights are being rerouted.
The crew of MH17 had no way to detect that a missile was headed toward the plane.
The information contained on the black boxes would be limited but could help determine a timeline for investigators.
