Unidentified gunmen shot dead lawyer and prominent television panellist Babar Qadri at Hawal area of Srinagar downtown Thursday evening.
The gunmen fired at Qadri from point blank at his residence, resulting in his instant death at around 6:30 pm, a Police officer said.
He was taken to SKIMS hospital where doctors declared him dead on arrival.
Following the attack, the area was placed under cordon.
However, the attackers had managed to escape by then.
No one has claimed responsibility for the attack.
A Police officer said that a case had been registered into the incident and investigation had been started.
Another senior Police officer said that all the angles were open in the case and would be probed.
The social media handles of the deceased advocate would be also looked into thoroughly, he said.
Qadri, who was in his early 40s, was a lawyer by profession, a regular debater on various TV channels, and a writer.
He used to appear on TV channels and debate on issues pertaining to Kashmir including the abrogation of Article 370 and bifurcation of Jammu Kashmir.
"Abolition of Art 370 and art 35 A was never done for the interest of Indian people rather it was done to promote capitalists. Soil & sand is being excavated by companies now, which was a source of livelihood to poor Kashmiri. Jhelum and Hokarsar is being dredged out by companies," Qadri, who had been a vocal critic of the government, tweeted on September 13.
His killing occurred barely three days after he had tweeted a screenshot and urged the Police to register an FIR against a Facebook user for spreading a "wrong campaign" against him.
"I urge the State Police administration to register FIR against this Shah Nazir who has spread the wrong campaign that I work for agencies. This untrue statement can lead to threat to my life," reads Qadri's last tweet on September 21.
He became the second person to be shot dead by unidentified gunmen within 24 hours.
On Wednesday night, a member of the Block Development Council in Khag area of Budgam district, Bhupinder Singh, was shot dead by suspected militants.
Qadri studied law at the University of Kashmir and started practicing law in 2008 at Jammu and Kashmir High Court, Srinagar.
Babar had reportedly escaped a life bid in 2018 when unidentified men intercepted his car near his Hawal residence after they found the lawyer was not inside the car which was at that time driven by his brother.
