Opposition forces in Libya are gaining ground, as rebel fighters prepare for "the worst" in the North African country, the Associated Press reports. While Col. Muammar Qadhafi still holds the Libyan capital of Tripoli, rebel forces have taken nearby cities, including the second largest city of Benghazi. They have also begun to train thousands of civilians. Meanwhile, some shops are beginning to reopen in Benghazi. Qadhafi sent convoys of medical supplies to the city in an effort, some say, to show he is still the country's only leader. But the opposition leaders are refusing to accept the goods. The United States has been urging Qadhafi to relinquish power and has even suggested exile for the Libyan leader who has ruled for over 40 years.
