MAZAR-I-SHARIF, Afghanistan (AFP) - Landslides buried a village in northern Afghanistan on Friday, killing at least 350 people and leaving thousands of others feared dead, as rescuers searched desperately for survivors trapped under the mud.

Villagers at the disaster site in Badakhshan province used shovels to dig through rocks and dirt, with national authorities, the United Nations and the US-led military force all racing to assess the damage and provide help.

Badakhshan governor Shah Waliullah Adeeb told AFP by telephone that the death toll could be as high as 2,500.

"Our initial findings based on local people's reports show around 2,500 people, including women and children, might be dead," he said. "It is difficult to get confirmed information from the scene and we are seeking to determine the facts."

Provincial officials said that two successive landslides hit Aab Bareek village within one hour as a hillside collapsed, engulfing hundreds of mud-brick homes.

Villagers were at Friday prayers in two mosques when they were swamped by a tide of debris, and the second landslide hit many who had rushed to assist those in need.

"The number of deceased has increased to 350," the UN mission in Afghanistan said in a statement. "A response is being mobilised for those who survived but were displaced, with some partners already on the ground.

"(NATO's) Regional Command in the north (is) in contact with the Afghan National Army in regards to search and rescue efforts," said the UN.

Badakhshan is a remote, mountainous province in north-east Afghanistan bordering Tajikistan, China and Pakistan.

It has been relatively peaceful since the US-led military intervention began in 2001, but has seen increasing Taleban activity in recent years.

President Hamid Karzai expressed his condolences to those affected and said immediate action was being taken to save survivors as emergency efforts continued after darkness fell.

Local officials said that the landslides occurred at about midday (0730 GMT) in the Argo district of Badakshan after days of heavy rain. Between 350 and 400 houses were destroyed, they said.

"It is a disaster. The landslide has affected around 1,000 families," Mr Sayed Abdullah Homayun Dehqan, provincial director of the Afghan National Disaster Management Authority, told AFP. "Around 300 families are missing, that could involve around 2,000 people. People are working to remove the rocks, so far three bodies have been recovered."

"Around 700 families were rescued, we have sent in some basic assistance such as tents and blankets," he added.

The UN was helping to coordinate authorities to find survivors, but warned that roads to the area could not take heavy machinery and that further landslides were a risk.

"The foremost priority at the moment is saving as many lives as possible of those still beneath the rubble," said Mr Mark Bowden, UN humanitarian coordinator in Afghanistan.
"The UN system is fully engaged in the ongoing effort and is mobilising more capacity and resources to bolster the response."

US President Barack Obama described the deaths as "an awful tragedy".

"We stand ready to help our Afghan partners as they respond to this disaster," he told a press conference in Washington with German Chancellor Angela Merkel.

The landslides follow recent severe flooding in other parts of northern Afghanistan, with 150 people dead and 67,000 people affected by floods in Jowzjan, Faryab and Sar-e-Pul provinces.

Nearly 3,500 houses were damaged and destroyed by the floods, creating an urgent need for shelter, clean water, medical supplies, and food.

The floodwaters swept through villages, inundating thousands of homes and leaving many people seeking safety on the roofs of their houses. The floods also destroyed farmland and killed livestock across the remote region.

Flooding and landslides often occur during the spring rainy season in northern Afghanistan, with flimsy mud houses offering little protection against rising water levels and torrents of mud.

In the last major flooding in Afghanistan, 40 people died in August in flash floods in eastern and south-eastern provinces and some districts of the capital Kabul.

Neighbouring Pakistan suffered the worst floods in its history in 2010, when almost 1,800 people died and 21 million people were affected.

Afghanistan is in the middle of presidential elections, with former foreign minister Abdullah Abdullah and ex-World Bank economist Ashraf Ghani due to compete in a head-to-head vote on June 7. Preliminary results from the first round of elections on April 5, in which eight candidates ran, showed none gained the 50 per cent needed for a decisive victory.
