Cyclone Idai has killed at least 150 people across southern Africa since last week when the tropical storm began ravaging many parts of the region, says the Red Cross.
More than sixty people have died in the east of Zimbabwe, including two boarding school pupils, while in neighbouring Mozambique, around ninety others are dead or feared missing.
In Zimbabwe, many of the casualties were recorded after a school dormitory was hit when rocks swept down a mountain.
According to the Red Cross, Idai has had a “massive and horrifying” impact on the Mozambican port city of Beira.
The cyclone made landfall on Thursday with winds of up to 177 kilometres an hour, but aid teams only reached Beira on Sunday.
People have been rescued from trees, homes destroyed and roofs ripped off concrete buildings, head of the Red Cross assessment team, Jamie LeSeur, told the BBC on Monday.
Mr. Leseur said the death toll in Beira, with a population of 500,000, was not yet clear.
But he also confirmed that locals have managed to put in an “incredible effort” to reopen roads in the beleaguered city.
