Militants hurled a grenade at a rally of the People's Democratic Party (PDP) in Gandwani, Kulgam, on Friday.
The grenade attack comes at a time when the various political parties have begun campaigning for the upcoming Jammu and Kashmir Assembly polls.
Earlier in the day, Congress president Sonia Gandhi addressed an election rally at Bandipora in Jammu and Kashmir.
The Jammu and Kashmir polls are scheduled to be held in five phases from November 25 to December 20. The counting of votes will be held on December 23.
