Massive avalanches roaring down a mountain pass north of Kabul may have killed more than 60 people Tuesday, Afghan officials said, as rescuers evacuated about 400 injured victims.

Search-and-rescue teams recovered the bodies of 24 people but said they fear 40 others may have also died, Interior Minister Hanif Atmar said. About 2,500 people were rescued from their snow-blocked vehicles.

"Twenty-four bodies have been recovered so far, but the fear is that there could be up to 40 more still buried and unfortunately, they might have died already," he said. "That's the best estimate we have at this moment."

Afghan and coalition forces evacuated about 430 injured, with 180 taken by coalition helicopters to Bagram Airbase for medical treatment, Defense Minister Gen. Abdul Rahim Wardak told reporters at a press conference in Kabul. The 250 others were taken to hospitals nearby.

The avalanches struck Monday following heavy snow along the 12,700-feet Salang Pass, which links the Afghan capital with the northern city of Mazar-i-Sharif.

"It happened all of a sudden and it took us by surprise," Atmar said.

Rescue operations managed to extricate about 2,500 uninjured people from the area, he said.

Some 500 Afghan soldiers were mobilized to join about 400 police and others in rescue efforts. The international coalition contributed four Chinook helicopters, while the army sent two choppers, several ambulances and several bulldozers, the Afghan National Army said.

Suhrab Ali Safari, acting public works minister, told The Associated Press in a phone interview from Salang a strong snowstorm overnight triggered a major avalanche that covered about 2 miles of road.

"Unfortunately, it has blocked the road completely. We're working to clear it from both sides, north and south," he said.

Safari said there was a series of smaller avalanches in the area in recent weeks. Soldiers, police and local people were all trying to help in the rescue efforts, he said.

"Everybody is trying to rescue the people who are stuck in the avalanche. But while we're clearing one part of the road, the storm covered another part of the road again. It's very difficult," he said.

Military helicopters were dropping food packages to people stuck on snow-blocked roads, Interior Ministry spokesman Zemerai Bashary said. Earlier, Afghan reports said some 300 cars and buses were trapped on the mountain pass.

In a statement, President Hamid Karzai ordered the ministries of public works, defense and disaster control to "use all possible means to get the roads unblocked and rescue those trapped and stranded in the heavy snow."

He also expressed condolences to the families of the victims who were killed or injured.
