The downpour began on Friday in West Pokot County, which borders Uganda, and worsened overnight, causing flooding and mudslides that swept away four bridges and left the worst-affected village, Muino, inaccessible by road, Presstv Reported.
“More people are marooned and the entire village is at risk of being wiped out by the floods,” the county’s governor, John Lonyangapuo, told Reuters by phone as he waited for a helicopter to transport him to survey the damage.
He added that rescue efforts were underway in the area, where more than 500 vehicles are stuck on roads damaged by the landslides.
Eleven of the people killed were in the same house, Lonyangapuo said.
