American analysts say they've verified several pieces of evidence that show pro-Russian separatist rebels shot down Malaysia Airlines Flight MH17, according to U.S. intelligence officials who briefed reporters Tuesday.
Here's a quick rundown of the officials' updates on what U.S. investigators have found, from notes taken by NPR's Pentagon reporter Tom Bowman:
A U.S. spy satellite detected the launch of a surface-to-air missile in the area just before the plane went down.
In the wake of the Malaysian airliner's downing, many Europeans are now calling for tougher sanctions against Russia. Among them is Radek Sikorski, Poland's foreign minister, who explains to Robert Siegel why the West should ratchet up sanctions.
