An international conservation group says gunmen have ambushed one of its vehicles and killed two people in an eastern Congo game park. World Wildlife Fund official Thierry Bodson says another three people were wounded in the attack in Virunga National Park on the border with Rwanda and Uganda. U.N-funded Radio Okapi said Wednesday that the vehicle was carrying 11 people when it was attacked late Monday. It says the two people killed were the wife of a park guard and her daughter. The park is home to some of the world's last remaining mountain gorillas, according to a report of the Associated Press.
