B767 flight crew experiences a critical ground conflict with a regional jet during initial turn afte...

Narrative:

I read back the taxi clearance in full and then the ground controller added; 'pass behind the rj that is joining alpha 7. He will turn on bravo.' I acknowledged and the captain and I both had the rj in sight. The rj was going to be well clear by the time we got to his position; so he was really not a factor. I cleared right and the captain began a slow taxi. As he started a slow right turn to join taxiway alpha; I took another look to verify the taxi way was clear since we were unable to see behind us on alpha due to our position being parallel to the alpha taxiway. I spotted an rj on taxiway alpha and he was coming up on our right wing. I shouted 'stop' to the captain. Due to the timeliness of the need to stop; I applied the brakes and brought the aircraft to a sudden stop to avoid a possible collision. The ground controller must have witnessed our stop because she said thanks for holding short. The captain then requested for me to contact the purser to make sure everyone was ok. I called the purser and she said they were tossed around a bit but they were ok. We proceeded with our taxi instructions and departed. During the flight; a flight attendant called from the back and was wondering what happened. She said that some of the flight attendants were a little sore from the ordeal and they were not informed by the purser what had taken place. The captain and I had assumed when I called the back that the purser would have checked with all the flight attendants. The captain then discussed the issue with all the attendants and all flight attendants were able to complete their in flight duties. The captain had the flight attendant supervisor meet the flight to discuss the details and extent of possible injuries. No serious injuries were reported at the time we left the aircraft.
