Jammu/Srinagar: Snowfall and heavy rains in Jammu and Kashmir disrupted air traffic in the state and forced the closure of 300-km-long Jammu-Srinagar National Highway.

"The Srinagar-Jammu National Highway has been closed due to snowfall on either sides of the Jawahar Tunnel in south Kashmir," an official of the traffic department said.

Almost four inch of snow has accumulated at Jawahir tunnel, while heavy rains continued to lash the state.

The air connectivity between Srinagar and other parts of the country was also affected as early morning flights were cancelled due to poor visibility.
