Floods in southern Mozambique have displaced up to 70 000 people and cut power exports to energy-hungry neighbour South Africa in half.
The south and centre of the country have been placed on red alert after experiencing the heaviest rainfall since devastating floods killed some 800 people in 2000.
Local media reports that as the Limpopo River raged through the southern town of Chokwe, people slept in the open as their houses became submerged.
The country's international humanitarian head Lola Castro told AFP that they were sending 7 days of food for 70 000 people.
She said helicopters would start rescuing people stranded on rooftops from Friday.
Earlier, 15 000 crocodiles escaped from a farm in South Africa as the Limpopo flooded upstream from Mozambique.
Key power lines to South Africa were also damaged by the flooding of the Limpopo.
