A faction of a separatist rebel group said on Sunday it was seeking peace talks with the Ethiopian government, a development that could help stabilize a region with potential reserves of oil and gas.The Ogaden National Liberation Front (ONLF) has fought since the mid-1980s for independence for the mainly ethnic Somali province of Ogaden in southeast Ethiopia, bordering lawless Somalia.Abdinur Abdulaye Farah, the group’s representative in east Africa, said his faction was in the Ethiopian capital hoping to have talks with the government. There was no immediate comment from the authorities.The initiative pointed to weakened secessionist activity in Ogaden, where rebels have not mounted a major attack since 2007. Several companies, including Chinese firms, are exploring for oil and gas in the area."More and more people want peace. There are very few people supporting the rebels now,” Farah told journalists upon arriving at Addis Ababa’s airport.A separate ONLF faction, which claimed to represent 80 percent of the fighters who menaced energy stakes in the Ogaden a few years back, sealed a deal with the Ethiopian government last year.Farah said negotiations between the remainder of the ONLF and the government, held in Kenya’s capital Nairobi two months ago, broke down when the rebels declined to accept the constitution and shun their armed struggle. The talks led to a further split, he said.Other rival wings within the divided ONLF, including one run by former Somali navy chief Admiral Mohamed Omar Osman, were not immediately available for comment.
