The fighting between Libyan leader Moammar Gadhafi's troops and the rebels who are against Colonel Gadhafi is getting worse. Libyan aircraft bombed two parts of the country yesterday where rebels have taken control. In this incident that you're watching, a CNN crew saw an aircraft drop two bombs near a town that has major oil and natural gas facilities.

U.S. officials say one option to try and push Gadhafi out of power is to create a no-fly zone over Libya. Defense⁴ Secretary Robert Gates says if Congress orders that, the U.S. military could do it. But he warned lawmakers that in order to set up the no-fly zone, first, the U.S. would have to attack Libya's anti-aircraft weapons.
