Assailants fatally shot a politician belonging to India's ruling party in occupied Kashmir, and separately, police on Thursday killed a detainee who they said snatched an officer's rifle and fired at officials inside a police camp.

The unidentified assailants shot Rakesh Pandita late on Wednesday in the southern town of Tral, where he was visiting a friend, police said, blaming rebels for the attack. He was declared dead in a hospital.

Rebels in occupied Kashmir have been fighting the central government for decades. Suspected militants carried out a string of deadly attacks last year on members of Prime Minister Narendra Modi's Bharatiya Janata Party (BJP) in occupied Kashmir.

Among those killed was a top BJP politician and his father and brother, who were also party members.

Pandita was also an elected official for a municipal office in Tral. His body was taken to southern Jammu city for a funeral.

He had a secured accommodation in the region's main city of Srinagar and was protected by two police guards, but he went to Tral without them, a police statement said.

Manoj Sinha, New Delhi's top administrator in occupied Kashmir, and BJP leaders condemned the killing.

"Terrorists will never succeed in their nefarious designs, and those responsible for such heinous acts shall be brought to justice," Sinha said in a tweet.

No group has claimed responsibility for the attack.

Meanwhile, a man was killed in an exchange of gunfire inside a counterinsurgency police camp in Tral town early on Thursday, police said, calling him a terror operative.

In a statement, police said Mohammed Amin Malik snatched an automatic rifle from an officer during his interrogation and fired at him, leaving the officer critically wounded late on Wednesday. He later took position inside the interrogation room, the statement said.

Police said they brought Malik's mother to the camp and tried to persuade Malik to surrender but he refused and intermittently fired at police throughout the night. The statement said police later engaged him in a gunfight and killed him.

Police said they arrested the 38-year-old labourer last Sunday and seized a hunting rifle without a license and explosives from him. According to police, Malik was a former militant. They said he was arrested in 2003 and was released a few years later, adding that his younger brother was killed in a gunfight with Indian troops in 2019.

Mughli, Malik's mother who uses only one name, told reporters that police tortured her son during his detention. "They beat my son so much that he preferred to die like this," she told reporters, as she wailed in mourning at her home in Tral.

In 2019, Modi's Hindu nationalist party pushed through with constitutional changes that stripped occupied Kashmir of its semi-autonomy and statehood that gave its residents special rights in land ownership and jobs.

The region was also divided into two federally governed territories. Many Kashmiris and critics have likened India's changes as the beginning of settler colonialism.
