GENEVA (AFP) - At least 80 civilians were killed and more than 100 others injured in violence in the Somalian capital Mogadishu in the last week of September, the United Nations said on Friday. Some 110 people have been admitted to two main hospitals in Mogadishu, but "the number of those wounded is suspected to be higher," said Elisabeth Byrs, spokeswoman of the UN's Office for the Coordination of Humanitarian Affairs (OCHA). About 15,000 people have also been displaced following the fighting, some fleeing to safer districts in the city, while others fled to the Afgooye corridor where already 300,000 internally displaced people have sought refuge. OCHA had appealed for 646 million dollars to help 3.2 million people or 43 percent of Somalia's population, which is in "dire need of humanitarian assistance". But Byrs said that the fund is still short of 231 million dollars. The UN refugee agency had earlier described the fighting in Mogadishu as the "most violent since February 2007", shortly after the toppling of hardline Islamists. It estimates that 700,000 people fled the capital last year, and another 160,000 have left since the start of the year. Somalia has had no effective government since the 1991 ouster of Siad Barre touched off a bloody power struggle that has defied numerous attempts to restore stability. Meanwhile, the negotiations to secure the safe release of a Ukrainian ship loaded with military hardware and hijacked off the coast of Somalia last week are making progress, a spokesman for the pirates said Friday. "We have no new development to report except that the negotiations with the owners of the ship are making progress," one of the pirates on the ship told AFP by phone. "I can't tell you when the issue will be resolved but the discussions are certainly encouraging," said the pirate, who did not want to give his name. The pirates have demanded a 20-million-dollar ransom be paid for the release of the MV Faina, which they seized on September 25. Piracy has been rampant off the coast of lawless Somalia in recent months, but the Ukrainian ship is the most spectacular catch to date, with a cargo of 33 combat tanks and other weaponry. "The crew members and the Somali men on the ship are safe and in good health," the pirate added. The MV Faina is currently moored off the coastal village of Hobyo, some 500 kilometres (300 miles) north of the capital Mogadishu. It is surrounded by a number of foreign warships, included US navy vessels tasked with monitoring the situation and ensuring that the military equipment is not offloaded to shore. More than 60 attacks on ships have been reported off the coast of Somalia since the start of the year.
