The festival is 'kicked off' with the ritual slaughter of five thousand buffalo in a field near the temple, after which two days of ritual animal slaughter takes place. 

Animal rights activists such as PETA are campaigning to halt the mass animal-slaughter, but despite their efforts, the organisers of the festival has promised that this year will be the biggest yet. 

About 2.5 million devotees  have turned out for the festival, according to local government official Yogendra Prasad Dulal, who said it was 'impossible to estimate' the total number of animals sacrificed so far.
