The accident happened within minutes of the helicopter taking off, on what should have been a 10-minute flight to a Hindu pilgrimage site in the Himalayas.

A helicopter carrying Hindu pilgrims has crashed in India, killing seven people on board.

The accident happened within minutes of the helicopter taking off, officials said, on what should have been a 10-minute flight.

The helicopter was flying to Guptkashi, a prominent Hindu pilgrimage site in the Himalayas, from Kedarnath temple town in the northern Indian state of Uttarakhand.

It comes three days after an Air India flight crashed less than a minute after taking off from Ahmedabad airport in northwestern India, killing at least 270 people.

The helicopter, which was operated by private helicopter service Aryan Aviation, went down in a forested area several miles from the Kedarnath pilgrimage route at around 5.30am local time.

Officials said the crash was believed to have been caused by poor weather conditions.

Authorities say they have launched a search and rescue operation and are expected to review operational protocols for flights in the region.

The dead include the pilot and pilgrims from the neighbouring state of Uttar Pradesh and western states of Maharashtra and Gujarat, according to officials. The bodies were badly burned in a fire that followed the crash, they said.

Tens of thousands of pilgrims visit Kedarnath, which is home to one of the four most sacred Hindu temple shrines, each summer. Many use helicopter services due to the difficult mountainous terrain.

Helicopter mishaps are not uncommon in the region, where sudden weather changes and high-altitude flying conditions can pose risks.

Earlier this month, a helicopter operating in the Kedarnath Valley made an emergency landing shortly after taking off on a highway due to a technical fault. The pilot was injured but all five passengers on board were unharmed.

In May, a helicopter crashed in Uttarkashi district, killing six people, including the pilot. One person survived.
