Two persons were killed in violence on Friday at Chak Mishri Khan village in Amritsar district, which is close to the international border.
The incident, in which three people were also injured, occurred hours before campaigning for zila parishad and panchayat samiti elections came to end. Polling for these rural bodies is scheduled for May 19.
Reports from Amritsar said the incident took place when two rival groups owing allegiance to the Shiromani Akali Dal and the Congress organised meetings on some issue.
Soon, heated arguments broke out and it took a violent turn as both sides started shooting at each other.
The deceased were identified as Gurjinder Singh and Balkar Singh from the Congress and Akali Dal camps respectively.
The police have registered a case against one Jagir Singh and 13 others. Jagir Singh was accused of shooting Gurjinder.
The police have sought to link the case with some ongoing enmity rather than poll-related violence.
Meanwhile, State Election Commissioner S.S. Brar, in a statement, said polling for 146 panchayat samitis and 22 zila parishads would be held on May 19. The civil and police administrations have been directed to make foolproof security arguments for smooth conduct of polls.
Mr. Brar further said 760 candidates were in the fray for 331 zones in zila parishads, where 30 others had been declared elected unopposed.
In the panchayat samitis, 5786 candidates were in the fray, while 238 were declared elected unopposed. Liquor vends would remain closed in rural areas across the State on voting day.
