Slain journalists' bodies shipped out of MisrataTRIPOLI: Libyan rebels said Thursday they had control of a post on the Tunisian border, forcing government soldiers to flee over the frontier and possibly opening a new channel for opposition forces in Muammar Gaddafi's bastion in western Libya. In the rebel stronghold of Benghazi in eastern Libya, meanwhile, relief workers and medical teams awaited the arrival of a passenger ferry carrying about 1,000 people — mostly Libyan civilians and workers from Asia and Africa — out of the besieged city of Misrata, the main rebel holdout in Gaddafi's territory. Also aboard the vessel were the bodies of an Oscar-nominated documentary maker from Britain and an American photographer who were killed covering clashes Wednesday. A day earlier, the ferry arrived in Misrata, delivering food and medical supplies to the beleaguered population. Rebels appear to be gaining more international support, including plans by Italy, France and Britain to send combat advisers and other nations pledging communications and other equipment under the NATO mission. But Gaddafi's regime fired back with fierce threats if the alliance sends any troops to Libya. “If NATO comes to Misrata, or any Libyan city, we will unleash hell upon NATO,” government spokesman Moussa Ibrahim told reporters in the capital Tripoli. “We will be a ball of fire. Libya will become one man, one woman, fighting for freedom. We will make it 10 times as bad as Iraq.” The reported capture of the border crossing followed three days of intense fighting outside the desert town of Nalut, about 240 km southwest of the capital Tripoli, said a rebel leader, Shaban Abu Sitta. The area was briefly in hands of anti-government forces last month before Libyan troops moved in. Holding the Dhuheiba border crossing could open important supply routes for anti-Gaddafi forces and give the rebels another foothold in western Libya. “Rebels are now manning Dhuheiba crossing,” said Abu Sitta, who claimed his fighters destroyed 30 army pickup trucks and captured 10 cars and some weapons. Tunisia's official TAP news agency said Libyan rebels had control of the post and at least 13 Libyan military officers, including two commanders, fled across the border. On the Ionian Spirit ferry — part of a maritime lifeline to Misrata – Libyan civilians and migrants workers packed the decks, hallways and every other available space. In the ship's Panorama Bar, evacuees tossed mattresses onto the wooden dance floor. Women slipped behind a curtain to change. TThe vessel carried the bodies of Chris Hondros, a New York-based photographer for Getty Images, and British-born Tim Hetherington, co-director of the 2010 Afghanistan war documentary “Restrepo” that was nominated for an Academy Award. The film was co-directed by Sebastian Junger, author of “The Perfect Storm.” They were killed Wednesday in an attack that also injured two other photographers. A statement from Hetherington's family said he was killed by a rocket-propelled grenade. The ship also held the body of a Ukrainian doctor killed Wednesday from an artillery blast, said Haslam of the IOM.
