Damn, this thing is getting ugly.

(CSM) — An army unit and militiamen loyal to Libyan leader Muammar Qaddafi blasted a mosque with antiaircraft missiles and automatic weapons Thursday, targeting protesters who had holed up inside. The attack, which occurred just 30 miles from Tripoli, comes as Qaddafi finds himself increasingly squeezed by antiregime forces and isolated internationally for his brutal attempts to hold on to power.

Protesters inside the mosque “suffered heavy casualties,” though estimates for numbers killed were not available from witnesses, the Associated Press reports.

The attack was reportedly carried out by a legion of mercenaries and Qaddafi’s personal security forces. The New York Times describes the mercenary brigade fighting with an increasingly isolated Qaddafi, who may have even been deserted by parts of the Libyan armed forces at this point.

Distrustful of even his own generals, Colonel Qaddafi has for years quietly built up this ruthless and loyal force. It is made up of special brigades headed by his sons, segments of the military loyal to his native tribe and its allies, and legions of African mercenaries he has helped train and equip. Many are believed to have fought elsewhere, in places like Sudan, but he has now called them back.

Witnesses said on Wednesday that thousands of members of this irregular army were massing on roads to the capital, Tripoli, where one resident described scenes evocative of anarchic Somalia, clusters of heavily armed men in mismatched uniforms clutching machine guns and willing to carry out orders to kill Libyans that other police and military units, and even fighter pilots, have refused.

Can we expect mass demonstrations across the Islamic world because of the burnt Korans? I’m guessing no.
