Heavy snowfall has closed the Salang Pass, and cut off power to parts of Kabul
A series of avalanches has struck north of the Afghan capital, Kabul, leaving at least 29 dead, officials have said.
Heavy snow in recent days in Panjshir province and the Salang Pass has blocked roads, cut off villages and caused several avalanches.
Acting provincial governor Abdul Rahman Kabiri told the BBC about 30 people in his province were still trapped.
Avalanches are relatively common in the area, with dozens dying in major incidents in 2010 and 2012.
Some reports describe local people digging through the snow with their bare hands in the struggle to rescue the trapped.
Officials say rescue efforts have been hampered by the treacherous conditions.
The deluge of snow came after a relatively mild and dry winter.
