Six rangers killed in DR Congo park attack
Six park rangers were killed after an attack on the famous Virunga National Park, in the eastern Democratic Republic of the Congo.
Officials blamed the attack on a militia known as Mayi-Mayi, one of several operating in the area.
Rangers were ambushed as they patrolled on foot inside the park, a spokesperson told the BBC.
Staff working in the park, which is home to endangered mountain gorillas, have often been attacked.
In April last year, 13 rangers were killed in a rebel ambush.
Several armed groups are operating in the troubled eastern region of DR Congo, where Virunga National Park - a Unesco World Heritage site - is based.
A park statement said preliminary inquiries suggested the rangers "were taken by surprise and had no opportunity to defend themselves" during the attack on Sunday morning.
He said another ranger seriously injured in the attack was receiving treatment and expected to make a full recovery,
A local government delegate, Alphonse Kambale, told AFP news agency that two Mai-Mai militants were also killed.
Nearly 700 armed guards work in Virunga - Africa's oldest nature reserve - where at least 200 have been killed in attacks dating back more than a decade, AFP reports.
