I had been using the number of 1,300 killed and 20,000 injured the siege of Tripoli. However, Breitbart is reporting;
"Four hundred people were killed and 2,000 wounded in three days of fighting between rebels and forces loyal to Moamer Kadhafi in the Libyan capital Tripoli, the head of the rebel council said Wednesday."
These number seem low given the use of airpower to support the rebels. I suspect this may be a downplay on the actual carnage.
