At least 79 people have been killed as a result of flooding, landslides and bridge collapses in the southern Indiana state of Kerala in the last week, officials have said.
The worst floods in nearly a century in the popular tourist destination have led to rising water, which has stranded tens of thousands of people.

Rain and floods have destroyed and damaged hundreds of houses in the past week and caused significant losses to crops in a state known for its spices and coffee.
Authorities asked tourists to stay away from the popular hill station of Munnar in Iddukki district because of flooding.
People have also been asked to avoid the Sabarimala hill shrine as the water level in the nearby rain-fed Pampa River was rising. Sabarimala, a Hindu pilgrimage centre in the mountain ranges of Pathanamthitta district, attracts around 45 million devotees each year.

Heavy rains forced state authorities to release excess water from dozens of dangerously full dams, sending a surge into its main river and causing floods downstream.
“Presently, 35 reservoirs in the state are releasing water. Many districts in the state are facing floods,” the state’s chief minister, Pinarayi Vijayan, said on Twitter.
Another 12 deaths were reported on Thursday, putting the death toll since 8 August at 79, according to The Times of India.
