Government bombardment pushes back Libyan rebels

BREGA, Libya (AP) - Libyan government forces unleashed a withering bombardment of rebels outside a key oil town today as an Obama administration envoy met with the opposition leadership in its de facto capital, a possible step toward diplomatic recognition. NATO said nearly a third of Libyan leader Moammar Gadhafi’s heavy weapons have been destroyed. But the alliance said Gadhafi’s forces had changed tactics in the besieged western city of Misrata by moving tanks and other heavy equipment to civilian areas to prevent pilots from targeting them.
