A woman threatened to kill herself after her Air Deccan flight from New Delhi to Indian Kashmir was cancelled due to bad weather, airline officials said on Saturday.
The unidentified passenger warned she would set herself on fire after the no-frills airline announced the cancellation of its scheduled flight Friday to Kashmir's summer capital Srinagar, citing snow on the runway.
"This woman and her lady companion were put on another Srinagar-bound flight which was not cancelled despite the bad weather," an Air Deccan official said.
The unusual threat came as scores of passengers left stranded at New Delhi's domestic airport due to thick fog in the Indian capital staged noisy protests, security officials said.
On Saturday, dozens of flights were delayed for several hours due to the fog, which reduced visibility on the runways to less than 75 metres (yards), an airport spokesman said.
"All domestic departures remained suspended in the early morning hours," the spokesman added.
Two Delhi-bound international flights were diverted to Pakistan and to the western Indian city of Mumbai, he said, adding that Indian President Abdul Kalam was also stranded at the airport due to dense fog.
Hundreds of people were sent to a specially built "fog transit shelter" as the airport's main terminals remained packed with hundreds of other passengers stranded due to bad weather in other regions, witnesses said.
A large number of inter-city passenger trains were also delayed due to fog in eastern and northern India, a spokesman from the state-run service said as rail stations bursting with stranded passengers reported chaotic scenes.
Delhi police department said a six-car pile-up occurred on a city motorway and reported three other weather-related accidents which, however, did not lead to casualties.
