A goat offering is a holy act for Hindu devotees

Nepal Airlines said the animals were slaughtered in front of the plane - a Boeing 757 - at Kathmandu airport.

The offering was made to Akash Bhairab, the Hindu god of sky protection, whose symbol is seen on the company's planes.

The airline said that after Sunday's ceremony the plane successfully completed a flight to Hong Kong.

"The snag in the plane has now been fixed and the aircraft has resumed its flights," senior airline official Raju KC was quoted as saying by Reuters.

Nepal Airlines has two Boeing aircraft in its fleet.

The persistent faults with one of the planes had led to the postponement of a number of flights in recent weeks.

The company has not said what the problem was, but reports in local media have blamed an electrical fault.
