The International Organisation for Migration has said that Cyclone Idai and its aftermath "could rank as the worst disaster to hit the region in decades".
Twelve people perched precariously on a branch of a mango tree, sheltering from the floodwaters of tropical Cyclone Idai which wrought devastation across southern Africa.
More than a thousand people are feared to have died in Mozambique alone while scores have been killed and more than 200 are missing in neighbouring Zimbabwe.
Cyclone Idai has killed at least 64 people in eastern Zimbabwe and destroyed homes, bridges and roads, making rescue efforts difficult, a government minister said on Sunday.
Zimbabwe's ministry of information announced that the "number of deaths is confirmed at 24 mainly from Chimanimani East," including two students, while at least 40 other people have been injured.
