Dense fog wreaks havoc in India

At least 14 people were killed and 25 injured when a bus traveling from Nepal to the eastern Indian state of Bihar fell off a bridge into a ditch due to fog overnight, a local police official said.

Poor visibility was hampering rescue work at the site, he said.

In the Indian capital New Delhi, many international and domestic flights were delayed as dense fog enveloped the city and some other parts of northern India, a weather office official said.

"The fog blanketed New Delhi just past midnight (Saturday), affecting air and also train services," the official said.

An official from Delhi's Indira Gandhi International Airport said many international and domestic flights were affected.

"There were some delays but it was not as bad as yesterday (Saturday) morning," he said.

The weather office official said "foggy conditions are likely continue for another day or two but the situation is expected to improve after that."
