Kathmandu (PTI): The Nepal Government on Thursday constituted a five-member probe commission to investigate into the Yeti Airlines plane crash at Lukla in Northeastern Nepal.

The probe commission headed by Co-attorney General Pushpa Raj Koirala will submit its report within two months period, officials said.

As per the preliminary investigations of the commission, the plane crash was caused by bad weather.

Yesterday, 18 people, mostly foreign trekkers to the world's highest peak Mount Everest, including 12 Germans and two Australians, were killed when the small Nepalese private airliner crashed at Lukla.
