In Libya, NATO fighter jets have reportedly resumed air strikes on the capital of Tripoli. At least two explosions were heard in the city earlier today. Meanwhile, forces loyal to embattled leader Col. Muammar Gaddafi have launched rockets into the rebel-held city of Misurata for the first time in several weeks. Four rebel fighters were killed and another 60 wounded on Tuesday in clashes with Gaddafi forces in a nearby town.
