In Libya, nine people have been killed and 51 injured in a fighting around the western rebel-held city of Misrata. AFP reports said that forces loyal to Muammar Gaddafi used heavy artillery to bombard the Dafnia sector at the western entrance to Misrata, and rebels in the city retaliated. NATO in the meantime regretted first civilian casualties in Libya. In a statement, the alliance acknowledged responsibility for civilian deaths in a Tripoli bombing raid that left nine dead, including two toddlers. The Alliance has blamed the weapons system's failure for the bombing of a residential area. Earlier, the Libyan authorities had said that nine people had died in the raid. A NATO woman official said over one thousand strikes were made in the last three months or so and over four thousand of those were strike sorties which means that they let go about four weapons every time. She said these are the first credible reports of civilian casualties caused by NATO.
