Two NATO air formations conducted a concerted strike on a former regime barracks and ammunition depot, as well as a headquarters, near Zliten on 8 August. Subsequent missions attacked two command and control facilities and a military staging post in Zliten and Khoms. At sea, HMS Bangor continued her long-standing mine countermeasures patrol off Misrata, where Colonel Gaddafi had repeatedly made unsuccessful attempts to deny the port to humanitarian shipping, while HMS Liverpool once again fired a barrage of illumination rounds to support NATO operations in the Zliten area.[42]
