JUBA, Sudan (Reuters) - Fighting between armed clan members and soldiers in southern Sudan killed at least 30 people over the weekend, southern army spokesman Kuol Deim Kuol told Reuters. Seven from the SPLA (southern army) were killed and seven wounded, Kuol said, adding that 16 fighters from the Gok Dinka clan were found dead and at least 30 people were wounded. Seven Gok Dinka civilians were earlier killed by crossfire as armed Gok Dinka tried to raid an army weapons store for guns to retaliate against another clan that had recently raided them. South Sudan is awash with guns after a long civil war that ended with a 2005 north-south peace deal. Inter-tribal fighting has claimed over 2,500 lives in the past year and the southern armys efforts to quash skirmishes have sometimes turned bloody. Aid agencies and analysts say the fighting is especially destabilizing ahead of national elections set for April. Southern officials have blamed Khartoum, saying it has deliberately exacerbated long-standing tribal rifts. After the attempt to seize weapons, the armed Gok Dinka, a sub-clan of the Dinka, the souths largest tribe, carried out a spate of attacks on an army base in Cueibet town, Lakes State, which continued until Sunday. Yesterday evening it became calm, Kuol said.
