Today marks the fourth day of the European and American campaign against Gadhafi’s forces in Libya. The U.N.-sanctioned military intervention was originally designed to establish a no-fly zone, but also seems geared to free up the rebels to take on the Libyan leader themselves. We’ll get the latest from reporters on the ground in Tripoli. Here in the U.S., the politics of intervention are heating up. Lawmakers on both sides of the aisle are questioning President Obama about the goals of the mission and top Republicans are ramping up their criticisms. And on Monday, the U.N. warned that Italy is facing a humanitarian crisis following the arrival of some 15,000 Tunisian boat people and fears that more migrants will flee there following coalition air strikes on Libya. Meanwhile, unrest continues in Yemen, Bahrain and now Syria.
