Violence during election campaigning in India has led to a heated exchange of words between rival politicians.
West Bengal state chief minister Mamata Banerjee has taken issue with the ruling BJP ahead of voting in the state on Sunday.
Unrest was reported during BJP chief Amit Shah's roadshow in Kolkata on Tuesday.
Clashes broke out between BJP supporters and protesters who were holding "Amit Shah go back" posters.
Some people suffered minor injuries and a few vehicles were set on fire.
The BJP said the protest was "orchestrated" and called it an "attempt to strangulate democracy".
