(CBS News) -- It's been a busy week here in Washington and around the world. Everyone is scrambling to make sense of Thursday's shocking developments in Ukraine: the deadly crash of Malaysia Airlines flight 17.
Credible information has been hard to come by, and the White House has been quietly cautious over the last 24 hours. But for now, we believe that the plane was shot down by a surface-to-air missile and it appears that pro-Russian rebels in Eastern Ukraine are possibly behind it. Perhaps it was an accident.
One American was killed in the crash. Most of the passengers have been identified as European nationals many from the Netherlands. The plane was carrying about 45 people from Malaysia as well, where the airliner is based.
The White House was quiet at first, and President Barack Obama was busy yesterday plugging his infrastructure agenda and raising money in New York. He blamed pro-Russian rebels this morning and called for an immediate cease-fire in the region. Still, many questions remain as to how this tragedy can be fully investigated in the tumultuous rebel-held territory.
The conflict in Ukraine has really heated up, but the region we were all watching earlier this week was the Middle East. After a week of Hamas rockets attacks and Israeli air strikes, Israel launched its highly anticipated ground invasion of Gaza.
Civilian casualties are expected to rise as Israeli troops try to destroy terrorist infrastructure in the densely populated Gaza Strip. President Obama said today he supports Israel's right to defend itself but stressed the need to minimize civilian losses.
