STORY: Eunice Wanjiku scoured where her cousin Anne Mumbi's house once stood on Wednesday (May 1) after devastating floods destroyed her home in Mai Mahiu, Kenya.

"For example, this is her child's jacket, that's her mattress, that is her broken bed, that is her roof and over there we can see some materials that belonged to her. That is why we suspect that she is buried here."

Wanjiku is not alone.

Families in Mai Mahiu are searching for loved ones who are still missing.

The Kenyan Red Cross said two more bodies were pulled out from the debris, but Mumbi was not among them.

Nahashon Igeria is Mumbi's brother.

"We have been searching with our bare hands unsuccessfully but the smell concentrated around here which makes us believe that she may be buried underneath here somewhere. She lived up there, not far away, so with the smell we are almost certain."

Across Kenya, floods and landslides have killed more than 180 people and forced hundreds of thousands from their homes since March, the government and the Red Cross said on Wednesday (May 1).

President William Ruto has deployed soldiers to aid search efforts in Mai Mahiu, but their heavy machinery has not yet reached the area where Wanjiku's family was digging.

Dozens more have been killed by heavy downpours in Tanzania and Burundi.

Scientists say climate change is causing more intense and frequent extreme weather events.
