A least 42 people have died, and "there are still more in the mud," Kihika told AFP news agency. The access for the rescue groups is complicated by washed-out roads and demolished houses blocking the way.
Flooding has also blocked a major road in the region, police spokesman Stephen Kirui told the Associated Press news agency.
