Libya's rebels beat a panicked retreat from withering rocket and tank fire along their western front lines Tuesday, adding to speculation that they cannot stand against Moammar Gadhafi's troops without international intervention.
The battlefield reversal on the outskirts of Gadhafi's hometown, Sirte, came a day after President Obama pledged that no U.S. ground forces would be used in Libya and outlined a strategy to "hasten the day when Gadhafi leaves power."
