Ahmedabad: At least six people, including three policemen, were injured after a minor altercation between two persons snowballed into a communal clash in central Gujarat's Petlad town in Anand district on Monday.

The clash prompted the police to lob as many as 24 teargas shells to disperse the mob comprising over 200 people, who were pelting stones at each other and damaging vehicles in a communally sensitive locality.
