(CNN) -- A South African peacekeeper was killed in an ambush on a U.N. convoy in the restive Sudanese province of Darfur on Thursday, the United Nations said.
Members of the U.N. Mission in Darfur were on their way to check out reports of recent violence in the northern part of the province when they came under heavy fire from automatic weapons and mortars, a UNAMID statement reported.
The peacekeepers returned fire, but one of their members died and three more were wounded, the mission said.
At U.N. headquarters in New York, Security Council members condemned the attack and demanded that Sudanese officials "swiftly investigate the incident and bring the perpetrators to justice.
It's the second fatal attack on the peacekeeping mission this month, after the October 2 killings of four Nigerian troops. A total of 43 UNAMID members have died since the peacekeeping force was deployed at the end of 2007.
