A 6 minute 17 second video, which has gone viral on social networking sites, shows the young militant commander in a white T-shirt sitting on a chair with his legs covered by a blanket and two assault rifles stand on the wall on each side.
Wani said militants have no option but to attack policemen in Kashmir.
"As you know, we have carried out attacks since the last month in which we targeted many policemen and army men. Policmen are our own but still they force us to attack them.
Asking policemen not to "harass" youth or put check-posts on the roads, Wani said "if any policeman loves his life, then he should perform his duty inside camps and police stations and not harass youth, not to place check-posts and not to act against us".

"Whosoever does this, he will be responsible for his own death," he said.
"Recently, a BSF officer had said that we have plans for attacking Amarnath Yatra, which is totally wrong. We have no plans to target Yatris nor will we attack them. They are performing their religious duties here and we have nothing to do with that," he said.
He, however, said if the government establishes Sainik colonies in the Valley, they will be targetted.
He also said his group would mount attacks if the government builds separate settlements for Kashmiri Pandits.
"The Hindus (Pandits), who are outside, can live at their own places where they have their houses and land and they will find us as their guardians. The separate colonies, which India is planning on the lines of Israel, are not acceptable and we will attack those separate colonies," he warned.
