Cyclone Idai is an “unprecedented natural disaster” that no-one could have predicted, a Mozambican minister has said
The UN has said the final casualty figure after Cyclone Idai tore through southern Africa more than a week ago will only be known once the flood waters have receded.
At least 417 people have now been declared dead in Mozambique, Land and Environment Minister Celso Correia has said.
The new figure puts the overall death toll at about 700 people across Mozambique, Zimbabwe and Malawi.
It is expected to rise further.
The United Nations Office for the Co-ordination of Humanitarian Affairs (OCHA) said on Saturday that the Buzi and Zambezi rivers were at risk of breaking their banks again.
“We’re going to have to wait until the flood waters recede until we know the full expanse of the toll on the people of Mozambique,” OCHA co-ordinator Sebastian Rhodes Stampa said.
Thousands remain trapped by the floodwaters, and many of the Mozambican government’s relief centres have only just started receiving food supplies – more than a week after the storm first struck.
Some 1.7 million people are said to be affected across southern Africa, with no electricity or running water in areas where homes have been swept away and roads destroyed by the floods.

On Friday, cases of cholera were recorded in Beira in central Mozambique.
The International Federation of Red Cross and Red Crescent Societies (IFRC) warned of the risk of other outbreaks, already noting an increase in malaria.
Idai made landfall near Beira, a city of 500,000 people, with 177km/h (106 mph) winds on 14 March.
Aid workers are slowly delivering relief, but conditions are said to be extremely difficult, with some areas completely inaccessible and helicopters scarce.
Aid groups said Mozambique had borne the brunt of flooding from rivers that flow downstream from neighbouring countries.
Nearly 90,000 Mozambicans are thought to be sheltering in temporary sites, while thousands of others are still stranded in floodwaters, AFP news agency reports.
“We are living an unprecedented natural disaster. A disaster that only matches major disasters,” Mr Correia said.
“Unfortunately, no-one in the region and in the world could predict a disaster of this size,” he said.
