A selfie is an image you take with your smartphone, usually taken during a day or a week, with your face blurred or covered in a mask.
It is a moment of celebration.
A suicide bomb, meanwhile, is a highly effective and deadly device.
A selfie can be taken with your eyes closed and the bomb hidden in your pocket.
The first suicide bombing in India took place in 2013 and killed more than 30 people, mostly women.
In March 2016, a suicide bomber killed more people in the capital, New Delhi.
In September 2018, a woman wearing a suicide vest blew herself up at a train station in Mumbai, killing six people.
But these images are not just a popular photo-sharing tool.
In the past, they were used as propaganda and as a means to get more people to join militant groups.
But in the past three years, suicide bombings have become more prevalent, particularly after the September attack in Mumbai.
A series of mass shootings have become commonplace across the country.
In May 2018, at least 19 people were killed in two attacks in the western Indian state of Rajasthan.
The attacks took place over three days, and targeted police stations, a mall and a police station.
