Malawi floods kill 170 and leave thousands homeless
The authorities in Malawi say at least 170 people have died in flash floods – a sharp rise on previous figures.
Heavy rain over the past month has swept many houses away and caused residents to flee to higher ground, some crossing the border to Mozambique.
Vice-President Saulos Chilima said more than 100,000 people had been displaced from their homes, mostly in the south.
Earlier this week, the government declared a third of the country to be a disaster zone and appealed for help.
The Malawian authorities have been using military helicopters and boats to reach some of those stranded.
The vice-president said more helicopters and boats were needed, as well as tents and food.
South African troops are being deployed in neighbouring Mozambique where at least 25 people have died and a major road has been destroyed.
