Homemade bombs exploded, killing three people and wounding 50 in the attack on Sunday that targeted a three-day event organised by the Christian-based religious movement a few miles northeast of the city of Kochi.
Police arrested a man after he posted a video claiming responsibility for the attack, accusing the religious group of being anti-national. Chandrashekhar used former U.S. secretary of state Hillary Clinton's 2011 quote "You can't keep snakes in your backyard and expect them only to bite your neighbours. You know, eventually those snakes are going to turn on whoever has them in the backyard" and used hashtags #HamasTerrorists and #KochiTerrorAttacks.
Kerala's chief minister Pinarayi Vijayan said Modi's Hindu nationalist party was trying to destabilise the state, home to millions of Hindus, Muslims and Christians.
