Rangers said on Tuesday they had stopped tourists entering Democratic Republic of Congo’s Virunga National Park during investigations into the kidnapping of two Britons there last week.
Gunmen ambushed Robert Jesty, Bethan Davies and their driver in Congo’s volatile eastern borderlands on Friday and released them three days later.
Park ranger Rachel Makissa Baraka, 25, was killed trying to defend them.
“The suspension of tourism is being undertaken as an additional precautionary measure whilst an investigation is undertaken surrounding the recent events,” the park said in a statement. It said the suspension would remain in place until June 4.
