Russian Proton Rocket fails to orbit satellites

A Russian Proton rocket failed during launch earlier today.  It seemed to lose thrust shortly after launch, pitched over and broke up just before hitting the ground.  Although no one was injured, there was some concern that the toxic rocket fuel could drift towards a populated area. 

The Proton rocket does not launch the Soyuz manned craft to the International Space Station. There is no word if all launches have been put on hold due to this mishap.
