SRINAGAR: The Indian army and air force troops worked through the night to rescue thousands of people stranded across Kashmir where more than 300 people have been killed in landslides and flash floods, an official said.

Six days of incessant rains in Indian-held Kashmir have left more than 120 people dead in the region's worst flooding in more than five decades, submerging hundreds of villages and triggering landslides, officials said.

O.P. Singh, a senior official, said Monday that most parts of Srinagar, the main city in Indian-held Kashmir were submerged.

Stranded residents were camping on their roof, waiting for rescuers. Prime Minister Narendra Modi has called the flooding a “national disaster”.
