KABUL, Afghanistan -- At least 186 people have been killed by a series of avalanches in northeastern Afghanistan. The increased death toll came on Thursday as crews struggled to clear incredible amounts of snow that buried several homes, according to officials.

A local official said there wasn't enough equipment available to clear the way and rescue people believed to be trapped.

A CBS News crew reached the top of one of the avalanche sites where men using shovels were trying to rescue a family they said was trapped under the snow. Three bodies were later pulled out: Fariq, 40, his son Sifatullah, 7, and Fariq's 3-year-old daughter Bibi.

The avalanches began on Tuesday in Panjshir Valley about 60 miles outside of Kabul. Recent snowfall has blocked a major road connecting the city to northeastern Afghanistan, further hindering efforts to bring relief to the disaster site.
