Former Jammu and Kashmir (J-K) Director General of Police (DGP) SP Vaid has criticised JKLF chief Yasin Malik's claims about briefing former PM Dr Manmohan Singh after meeting Hafiz Saeed in Pakistan. "What could be more shameful than this?" Vaid questioned. He added that it was shocking that someone involved in killings was used for "diplomatic purposes" by the government.
