The death toll from flooding in northern Tanzania triggered by severe rains this weekend has increased to 63, according to the prime minister, adding to hundreds of other casualties throughout East Africa since seasonal rains began in October.

In statements shown on television, Prime Minister Kassim Majaliwa stated that 116 people had been hurt. He said that landslides had devastated half of one community he visited.

“We are here in front of bodies of our fellows. We have lost 63 loved ones. Of the total fellows we lost, 23 are men and 40 are women,” he said during an event to bid farewell to the bodies of those who had died in Hanang district, northern Tanzania.

“My fellow Tanzanians, this is a tragedy,” he said.

Earlier on Monday, President Samia Suluhu Hassan had put the number of dead at 57 and those injured and receiving treatment at 85.

Zuhura Yunus, a spokesperson for her office, said the floods and landslides had affected 1,150 households, or 5,600 people, with 750 acres of farmland destroyed.

Severe flooding caused by the El Nino and Indian Ocean Dipole weather phenomena has forced hundreds of thousands from their homes in Kenya, Somalia, Ethiopia and Tanzania since the rains began.

The flooding comes on the back of the worst drought to hit the region in 40 years. Dry soils are less able to absorb water, increasing the risk of flash-flooding.

Yunus said Hassan would shorten her trip to the COP28 climate talks in the United Arab Emirates to oversee the response to the incident.

“Despite all the challenges rescue work is facing from damaged roads and mud and logs filling the roads, the government is doing its best to deal with that,” Yunus said.

Queen Sendiga, commissioner of the Northern Manyara region, told reporters late on Sunday that authorities were still searching for bodies trapped in the mud.

Around 100 houses in the village of Katesh, Hanang district, were swallowed by a landslide, Sendiga said, adding that they did not know the whereabouts of people from 28 households.

Television footage showed streets turned into fast-flowing rivers of mud carrying debris past flooded houses.

Climate change is causing more intense and more frequent extreme weather events, according to climate scientists.

In response, African leaders are pushing for new global taxes and changes to international financial institutions to help fund climate change action.

In neighbouring Kenya, where floods have so far killed at least 154 people, the banks of the Voi River in the country’s south burst on Monday, the Kenya Red Cross said.
