Gunmen prepared to fight against Libyan leader Moammar Gadhafi stand on a small military truck with weapons taken from a Libyan military base, in Benghazi, Libya, on Thursday Feb. 24, 2011. Army units and militiamen loyal to Moammar Gadhafi struck back Thursday against rebellious Libyans who have risen up in cities close to the capital, attacking a mosque where many were holding an anti-government sit-in and battling others who seized control of an airport. Medical officials said 15 people were killed in the clashes. (AP Photo/Hussein Malla)
