Unknown assailants shot dead an election hopeful and two other people in Pakistan's North Waziristan region on Wednesday.

The independent candidate, identified as Kaleemullah Khan, was eyeing to contest polls for Khyber Pakhtunkhwa Assembly's PK-104, the law enforcers informed Geo News.

Police told the news channel that the incident occurred in the Tappi village of the district when Kaleemullah was busy with his election campaign.

"He was injured in a bomb blast recently as well," the law enforcers said.

Pakistan is witnessing an alarming spike in terrorism incidents in recent times.
