At least 230 people were killed when a fuel tanker overturned and exploded in eastern Democratic Republic of Congo, unleashing a fire ball that tore through homes and cinemas packed with people watching World Cup soccer.

Officials said on Saturday the explosion late on Friday also injured 196 people, adding that the death toll could rise.

They described scenes of devastation in the town of Sange, where houses were burned and bodies littered the streets. Some people died while trying to steal fuel leaking from the tanker, but most were killed at home or watching World Cup soccer in cinemas.

Many of the bodies were charred beyond recognition.

United Nations helicopters began airlifting injured people to hospital, while Congo's army, which lost a number of men in the blast, has sent soldiers in to help with the rescue.

"Our latest numbers are 230 dead and 196 injured," Madnodje Mounoubai, a spokesman for the UN mission, said. Congo's government also gave the same number of dead.

Marcellin Cisambo, governor of South Kivu province, where the incident took place, said the blast occurred when the fuel truck overturned, leaked fuel and then later exploded.

It was not immediately clear what caused the initial accident or later blast, but local people said the truck, which was part of a convoy, stopped when the road seemed to crumble, toppling the vehicle and spilling fuel. Fire then erupted.

"It's a terrible scene. There are lots of dead bodies on the streets. The population is in terrible shock - no one is crying or speaking," Jean-Claude Kibala, South Kivu's vice governor, said from Sange, which is between the towns of Bukavu and Uvira.

"We are trying to see how we can coordinate with (the U.N.) to manage the situation and how to take the wounded to hospital," he added.

Roads in the area are notoriously bad after years of war and neglect in the vast central African nation.

"Some people were killed trying to steal the fuel, but most of the deaths were of people who were indoors watching the (World Cup) match," Cisambo said.

There have been numerous similar accidents across Africa, where crowds gather around fuel tankers involved in crashes, only for the tanker to explode.

Millions of football fans across Africa were watching Ghana, the continent's last team in the World Cup, play Uruguay in the quarterfinals of the tournament on Friday evening.

For many, who have no electricity at home, makeshift cinema halls are the only option for watching the football.

"My children were watching the football match in the cinema and then they ran out to see the petrol," said Kiza Ruvinira, who lost three children and his sister-in-law in the blast.

"I went out to see what happened and I found my three children's bodies myself. I don't know how to go on."

Mubaya Mumasura also lost three family members: "I don't know what to do with myself I am so sad. I want the government to assist all the victims and help us."

Congo's weak government has difficulty providing even the most basic services, so U.N. peacekeepers began airlifting some of the wounded to nearby hospitals and aid workers were called in to help with medical treatment.

"The national Red Cross is working on collecting the bodies and taking them to the morgue, but the priority is obviously to take the wounded to the hospital," International Committee of the Red Cross (ICRC) coordinator Inah Kaloga told Reuters."

Kaloga said aid workers were trying to identify bodies before they were buried, but many were completely charred.

"It's a catastrophe," said Captain Olivier Hamuli," spokesman for Congo's military operation in South Kivu, adding that 13 soldiers had been injured and another 10 were missing.

The Kenyan driver of the truck is being held by the police.

Alain Ilunga, deputy CEO of Congo's storage and distribution company, which is already investigating the incident, said the truck was carrying 49,000 liters of petrol at the time.-Reuters
