CNN’s Baghdad Bureau Chief Cal Perry blogs about a bombing of Iraqi Deputy Prime Minister Salam al-Zubaie’s compound and what happened behind the scenes to report it…

I’m filming much in part because my personal security guards helped me past the very shaky and stunned guard force. We slowly made our way past guards running in each direction, showing our palms the entire time.

I’m keeping the camera low by my legs, to draw less attention.

The head of security for the deputy prime minister has given me permission to film. Granted, he gave me the permission while he was washing blood from his face. Without question — you can see it on his face — he’s in a complete state of shock.

I’m only filming for about 2-3 minutes when we can feel the situation changing. The Iraqi police are on the way and will be here at any moment. We walk outside, and try to make our way around the building so I can get some video of the damage caused by a second explosion — a car bomb that quickly followed the suicide bomb.

It’s maybe 30 seconds before the Iraqi police arrive, and they’re even more jumpy than the ministry security who actually lived through the explosion. Usually Iraqi police fire into the air, an announcement of their arrival.
