S.African rescuers in desperate search for dozens missing in floods

Police, army and volunteer rescuers on Friday widened the search for dozens still missing five days after more than 340 people died in the deadliest storm to strike South Africa's coastal city of Durban in living memory.

The "unprecedented" floods, which affected nearly 41,000, left a trail of destruction and at least 341 people dead.

With the government  coordinating the search-and-rescue operation, the official number of people missing in KwaZulu-Natal province stood at 55.

A fleet of cars and helicopters carrying police experts set out early Friday to comb through a valley in Marianhill suburb, west of Durban, to look for 12 people reported missing in the floods.

It is an increasingly desperate search for survivors.

Travis Trower, a director for the volunteer-run organisation Rescue South Africa, said his teams had found only corpses after following up 85 calls.

"It's unfortunate, but we do the best we can for as many people as we can," he said at a small airport north of Durban, one of the rescue hubs

Thousands of survivors, left homeless after their houses were destroyed, are being housed in shelters scattered across the city, sleeping on cardboard sheets and mattresses laid on floors .

Meanwhile volunteers, with hand gloves and trash bags, fanned across the city's beaches to pick up debris left by the massive storms ahead of an expected surge of Easter weekend holidaymakers.

Software manager Morne Mustard, 35, was among the scores of volunteers, who included children, picking up debris and  broken reeds from Durban's famous Umhlanga beach.

"This is my local beach where I bring my kids, and this is where we spend our weekend, so this is for our community,".

He roped in workmates, families and friends to help clean up as beach restaurants offered free breakfast for the volunteers.

Recalling the day the rain fell, Mustard said, "It didn't feel real, absolute devastation, a horrendous sight, stuff spilling out on the beach must have come from someone's house... brooms and mops, household utensils, it was such a heart sore to see."

Some of Durban's poorest residents lined up to collect water from burst pipes and dug through layers of mud to retrieve their scant possessions.

President Cyril Ramaphosa declared the region a state of disaster to unlock relief funds.
