The Jammu Kashmir Joint Awami Action Committee has accused Pakistan of withholding the bodies of slain activists, sparking further unrest in Pakistan-occupied Jammu and Kashmir.
Protests have continued for the third consecutive day, with one activist killed and several injured during a confrontation with law enforcement near Rawalakot.
The group has demanded the return of the bodies, release of detained members, and withdrawal of the ban on the organisation.
Amnesty International has condemned Pakistan's crackdown on protests, accusing authorities of using excessive force and violating human rights.
