BEIRA, Mozambique — More than a thousand people are feared to have died in a cyclone that smashed into Mozambique last week, while scores were killed and more than 200 are missing in neighboring Zimbabwe.

The city of Beira in central Mozambique bore Cyclone Idai’s full wrath on Thursday before the storm barreled on to neighboring Zimbabwe, unleashing fierce winds and flash floods and washing away roads and houses.

“For the moment we have registered 84 deaths officially, but when we flew over the area... this morning to understand what’s going on, everything indicates that we could register more than 1,000 deaths,” Mozambican President Filipe Nyusi said in a nationwide address.

“This is a real humanitarian disaster,” he said. “More than 100,000 people are in danger”.

Survivors have taken refuge in trees while awaiting help, the president added.

Aerial photographs released by a Christian non-profit organization, the Mission Aviation Fellowship, showed groups of people stuck on rooftops with flood waters up to window level.

“The scale of damage... (in) Beira is massive and horrifying”, the International Federation of Red Cross and Red Crescent Societies (IFRC) said.

Ninety percent of the city of some 530,000 people and its surrounding area has been “damaged or destroyed,” it said in a statement.

“The situation is terrible. The scale of devastation is enormous,” the IFRC’s Jamie LeSueur said.

“Almost everything is destroyed. Communication lines have been completely cut and roads have been destroyed. Some affected communities are not accessible.”

A large dam burst on Sunday and cut off the last road to Beira, he said.

Sofala province governor Alberto Mondlane warned that the “biggest threat we have now, even bigger than the cyclone, is floods because it’s raining more and more”.

Emma Beaty, coordinator of a grouping of NGOs known as Cosaco, said: “We’ve never had something of this magnitude before in Mozambique”.

“Some dams have broken, and others have reached full capacity, they’ll very soon open the floodgates. It’s a convergence of flooding, cyclones, dams breaking and making a potential wave: everything’s in place so we get a perfect storm.”

Nyusi said the Pungwe and Buzi rivers in central Mozambique “have burst their banks and engulfed entire villages.”

“Communities are isolated and bodies are floating” on the waters, he said.

Beira international airport was closed because of cyclone damage but later reopened.

In neighboring Zimbabwe, Idai left 98 dead and at least 217 more missing, according to the information ministry.

Families started burying their dead on Monday in damp graves, according to an AFP photographer.

The storm swept away homes and ripped bridges to pieces, leaving destruction that acting defense minister Perrance Shiri said “resembles the aftermath of a full-scale war”.

Some roads were swallowed up by massive sinkholes, while bridges were ripped to pieces by flash floods.

“This is the worst infrastructural damage we have ever had,” Zimbabwe’s Transport and Infrastructural Development Minister Joel Biggie Matiza said.

The eastern district of Chimanimani was worst-hit, with houses and most of the region’s bridges washed away by flash floods.
