The Indian state of Goa has identified 24 “no-selfie zones” along its coastline after a spate of deaths and injuries.

Signs warning against taking selfies have sprung up in recent days on cliffs, popular beaches and swimming holes in the state, which attracts about six million tourists each year.

The safety push comes after two tourists from Tamil Nadu state died on separate incidents on 17 June after climbing onto rocky outcrops in the ocean to take selfies. Both were swept away by large waves and drowned, police said.

Warning signs are already posted in many areas considered to be dangerous but are routinely ignored by people trying to get the perfect shot.

“The need for red alerts now is urgent,” the head of the private lifesaving company that monitors beaches in the state, Ravi Shanker, told the Indian Express. “The indifference to the law has started to cost heavy. It also has to do with a poor understanding of water and lack of awareness of a healthy beach culture.”

There are more selfie deaths in India than any other country in the world, according to a 2016 study. The survey found there were more than 127 reported deaths worldwide from selfies in 2014 and 2015 – most related to heights, vehicles or water.

Of those, 76 deaths occurred in India, including a 2014 incident in which 10 young people tried to take a selfie while on a lake in Maharashtra. They tipped the craft and seven died.

In another incident in January a man from Hyderabad was filming himself standing beside tracks as a train was passing. He misjudged the distance and was hit by the train and left with severe injuries.

Pakistan had nine selfie-related deaths, the second-highest number, while there were eight in the US.

A Briton and Australian were found dead earlier this month at the foot of a 30-metre cliff in the Portuguese town of Ericeira. Rescue officials suspect the couple had been trying to take a selfie when they fell.
