Mr Hussain said gusty winds in the area uprooted a huge pine tree that hit the cable of the coach, bringing it down to the ground.
Police rescued about 150 people stranded due to the snapping of a cable vehicle ropeway today at the famous ski-resort of Gulmarg in north Kashmir's Baramulla district.
Though the details are hazy and unclear, reports said speedy winds uprooted a pine tree and it hit the cable auto. Gulmarg is a winter ski destination but also popular with tourists during the current summer season.
Director Tourism Kashmir said the administration has made every effort to take back the cabin and fix the ropes and ferried stranded tourists back to Gulmarg bowl.
The accident was the first since the cable cars were installed 18 years ago, Hussain said.
He said the chief minister has asked the inquiry to probe the causes or lapses, if any, that led to the tragedy.More news: Australian Open: Srikanth beats Praneeth, reachs semis

Sources said the service has been stopped and operations are underway to rescue tourists who are stranded in 15 other cable cars.
The injured persons were shifted to hospital.
Mufti, who was herself monitoring the rescue operations, announced ex gratia relief of Rs. The cable vehicle has the capacity ferry 600 people in one hour.
The first stage of the cable vehicle transfers people from the Gulmarg resort at 2,600 meters (8,530 feet) to Kongdori station in the bowl-shaped Kongdori valley, according to the company which operates the cable auto.
"What awful news", he tweeted.
Former Chief Minister and opposition National Conference (NC), Omar Abdullah, while expressing his condolences in a series of tweets, questioned why the service was not shut down during high winds as a precautionary measure. "That's a laid down SOP (standard operating procedure)". The gondola service is the second-highest in the world, taking passengers up to a height of 4,200 meters (137,000ft) above sea level.
