Maj. Beverly Mock, a U.S. military spokeswoman aboard the USS Mount Whitney, which is the command and control center for the operation, said the strikes hit only targets that constituted a "direct threat to allied assets or civilians on the ground" and involved a "high degree of coordination between aircraft and personnel on the ground."
"[The strikes] they have been very effective," said Jalal ElGallal, a Libyan opposition spokesman in Tobruk. "Collateral damage is acceptable, as sad it is, because otherwise the casualties will rise to unacceptable proportions."
"Today there is hope, there is light at the end of the tunnel, there is a concentrated effort, the world community at long last stood up to impose the resolution they have passed," he said.
