The UN refugee agency said Wednesday it had resumed repatriating some of the tens of thousands of Sudanese refugees from Uganda after the operation was suspended last week, DPA reported. This happened after unknown gunmen had killed 41 civilians in ambushes in southern Sudan. "The operations resumed yesterday and 185 Sudanese were taken back home through convoys," the organization's spokesperson in Kampala Roberta Russo said Wednesday. "We decided to resume the operations as the Sudan border was reopened and the security situation has returned to normal. UNHCR has decided to resume the operations." The gunmen, widely suspected to belong to the Ugandan rebels of the Lord's Resistance Army LRA, carried out a series of ambushes on the bushy roads of southern Sudan on October 18, killing 41 people and injuring an unconfirmed number of others.
