Operation Density (or "Operation Specific Weight", Hebrew: מבצע משקל סגולי‎), also known as "The Fajr Night", was a Military operation conducted by the Israeli Air Force on the second day of the 2006 Lebanon War. In the operation, official Israeli military sources claim that the majority of Hizbullahs’ long-range rockets were destroyed in air strikes that lasted 34 minutes. Other sources question that the attack had any apparent affects on Hizbullah capabilities.
