At least six people were killed and dozens more wounded in Benghazi on Friday when rockets hit a group that had gathered to protest a United Nations proposal for a unity government to end a political crisis, hospital workers said. More than 2,000 people had gathered in Al Keesh Square in Benghazi to demonstrate against the proposal when at least seven rockets hit the crowd, the workers said. Libya is caught in a conflict that pits the internationally recognized government and its backers against a rival government set up by an armed alliance that took over the capital, Tripoli, last year.
