Seven people were killed when flash floods hit as they were trekking through Kenya's Hell's Gate national park, authorities said on Monday.
The victims, all Kenyan nationals, were part of a church youth group in a walking safari at the park located to the north-west of Nairobi.
"The seven people had gone missing just before dusk, when the group encountered sudden flash floods," the Kenya Wildlife Service said in a statement.
Kenya's main rainy season between March and May often causes floods and massive displacement across the east African country.
At least eight people perished earlier this month in a Nairobi slum when their homes were destroyed by boulders after a night of heavy rainfall.
