Dozens of people are feared to have been buried in
an avalanche near the recently-reopened Salang Tunnel connecting north
and south Afghanistan, the United Nations says.
"Attempts are under way to save the people and get them out," Yusuf
Hassan a UN spokesman in Kabul, told a news conference.
"At least 20 vehicles have been trapped," he said.
Mr Hassan said the UN had received a call for help from the interim
authority but that there was no snow clearing equipment in the vicinity
of the tunnel, which is located on a steep mountain pass about 80 kilometres
(50 miles) north of Kabul.
Recently reopened
The UN has joined efforts with teams from the International Committee
of the Red Cross and the International Security Assistance Force, he
said.
Mr Hassan said the route is mainly used by buses, minibuses and trucks
travelling between Kabul and Mazar-e-Sharif in the north.
People returning to the capital said a traffic jam had developed about
100 kilometres (60 miles) north of Kabul on the road to the Salang Tunnel.
The Soviet-built Salang - the world's highest tunnel at 4,100 metres
(13,350 feet) - was reopened to traffic only last month after being
blocked for years by fighting.
