RAS LANOUF: Libyan rebels said Monday they will regroup and bring in heavy weapons after forces loyal to Moammar Gadhafi pounded opposition fighters with helicopter gunships, artillery and rockets to stop the rebels' rapid advance toward the capital. An airstrike hit Ras Lanouf, a key oil port held by the rebels, on Monday but there were no casualties. A day earlier, a heavy assault by pro-regime forces stalled the rebel advance. Mohamad Samir, an army colonel fighting with the rebels, told The Associated Press that his forces need reinforcements from the east after Sunday's setback. "The orders are to stay here and guard the refinery, because oil is what makes the world go round," said rebel fighter Ali Suleiman, speaking at one of the checkpoints set up around Ras Lanouf. Sunday's fighting appeared to signal the start of a new phase in the conflict, with Gadhafi's regime unleashing its air power on the rebel force trying to oust the ruler of 41 years. Resorting to heavy use of air attacks signaled the regime's concern that it needed to check the advance of the rebel force toward Sirte — Gadhafi's hometown and stronghold. Anti-Gadhafi forces would get a massive morale boost if they captured Sirte, and it would clear a major obstacle on the march toward the gates of Tripoli. The uprising against Gadhafi, which began Feb. 15, is already longer and much bloodier than the relatively quick revolts that overthrew the longtime authoritarian leaders of neighboring Egypt and Tunisia. Libya appears to be sliding toward a civil war that could drag out for weeks, or even months. Both sides seem to be relatively weak and poorly trained, though Gadhafi's forces have the advantage in numbers and equipment. Hundreds if not thousands of people have died since Libya's uprising began — tight restrictions on media make it near impossible to get an accurate tally. More than 200,000 people have fled the country, most of them foreign workers. The exodus is creating a humanitarian crisis across the border with Tunisia — another North African country in turmoil after an uprising in January that ousted its longtime leader. The turmoil is being felt more broadly still in the form of rising oil prices. Libya's oil production has been seriously crippled by the unrest. The conflict in Libya took a turn late last week when government opponents, backed by mutinous army units and armed with weaponry seized from storehouses, went on the offensive. At the same time, pro-Gadhafi forces have conducted counteroffensives to try to retake the towns and oil ports the rebels have captured since they moved out of the rebel-held east. An opposition force estimated at 500 to 1,000 fighters has been cutting a path west toward Tripoli. On the way, they secured control of two important oil ports at Brega and Ras Lanouf. If the rebels continue to advance, even slowly, Gadhafi's heavy dependence on air power could prompt the West to try to hurriedly enforce a no-fly zone over the country. The UN has already imposed sanctions against Libya, and the US has moved military forces closer to its shores to back up its demand that Gadhafi step down. Enforcing a no-fly zone could take weeks to organize, however, and US Defense Secretary Robert Gates has noted that it must be preceded by a military operation to take out Libya's air defenses. British Foreign Minister William Hague said Sunday that a no-fly zone over Libya is still in an early stage of planning and ruled out the use of ground forces. As fighting across Libya grew fiercer, the international community appeared to be struggling to put military muscle behind its demands for Gadhafi to give up power. UN Secretary-General Ban Ki-Moon spoke to Libyan Foreign Minister Musa Kusa on Sunday, and called for an end to hostilities, according to a UN statement, which said Kusa agreed to the immediate dispatch of a humanitarian assessment team to Tripoli. Valerie Amos, United Nations under-secretary-general for humanitarian affairs and emergency relief coordinator, said in a statement that the Benghazi Red Crescent reported that Misrata was under attack by government forces. "Humanitarian organizations need urgent access now," she said. "People are injured and dying and need help immediately."
