Cape Town mayor declares major incident as roads closed and 80,000 people left without electricity

Extreme rain and strong winds across South Africa’s Western Cape province have caused flooding, torn off roofs, destroyed crops and damaged roads this week. It is estimated that the 48-hour rainfall totals between Sunday and Monday were between 100mm to 200mm (4-8in) in this region.

According to the Cape Town Disaster Risk Management Centre, 12,000 people were affected, but a further 80,000 people were left without electricity, according to the national power utility. The mayor of Cape Town signed a major incident declaration for additional resources and relief measures as 80 roads have been closed, 200 farm workers have been stranded and rail services have been suspended in the Western and Eastern Cape provinces.

Tanzania government blamed for violence against villagers in national park, while thousands more people face losing their homes

The World Bank is investigating allegations of killings, rape and forced evictions made by villagers living near the site of a proposed tourism project it is funding in Tanzania.

• ‘It’s a torment’: refugee tells how his family died in desert

Migrants from sub-Saharan Africa have spoken of their horror at being forcibly returned to remote desert regions where some have died of thirst as they attempt to cross the border into Tunisia.

• ‘I had to drink my own urine’: Africans tell of being forced back into desert at Tunisia border

Pato Crepin had walked for three days through the desert and could not take it any more. Twice, he and his family tried to cross the border from Libya into Tunisia; twice, they had been pushed back. Crepin, who was recovering from an infection and had not had a drink for 24 hours, found he could not get up. In the blistering heat of the mid-July desert, his legs had given up.

His wife and six-year-old daughter, however, seemed stronger. Crepin, an asylum seeker from Cameroon, believed that if they left him behind they might yet make it to Tunisia and, from there, perhaps, on to Europe. He did not want to slow them down. “Go,” he told them. “I’ll catch up with you in Tunisia.”
