A Libyan rebels walks towards a checkpoint in the outskirts of Ras Lanouf, eastern Libya, Sunday, March 27, 2011. Libyan rebels took back a key oil town and pushed westward Sunday toward the capital, seizing momentum from the international airstrikes that tipped the balance away from Moammar Gadhafi's military. Brega, a main oil export terminal in eastern Libya, fell after a skirmish late Saturday and rebel forces moved swiftly west, seizing the tiny desert town of Al-Egila a collection of houses and a gas station on their way to the massive oil refining complex of Ras Lanouf.
