Veer succumbed to his injuries during treatment at the government medical college hospital in Rajouri around midnight, sources said.

The body been handed over to the family for last rites, they said.

The BJP strongly condemned the attack and appealed to the police to immediately arrest those responsible for it. The incident triggered protests by locals and the BJP leader's kin who alleged Singh was not provided enough security.

Singh was also injured in the attack.

Terming the incident an act of cowardice, J&K BJP chief Ravinder Raina said terror attacks on BJP leaders were being orchestrated by Pakistan.

"We strongly condemn the attack. Police should immediately arrest the terrorists responsible for it," he said.
